Nearly all of her inbounds gear testing takes place at Crested Butte Mountain Resort, a couple of miles away from her shoveling habitat. 

These second-skins had been used climbing, tenting, mountain climbing, looking, ranching, farming, path working, backcountry touring, snowboarding, snowboarding, and snowball combating. We adventured throughout North Dakota farmlands, up cracks in Utah’s Indian Creek, and all through Colorado’s high-elevation peaks and limestone partitions.

In spring 2022 and 2023, Crested Butte Mountain Resort was the host location for the official GearJunkie Ski and Snowboard week, the place our workforce meets to check upcoming hardgoods and softgoods.

Our Testing Course of

Our workforce subject checks all the girls’s base layers which can be included on this information. Whereas the Smartwool and REI base layers constructed for prolonged sizes haven’t but been subject examined, we’re onboarding plus-size testers for the winter of 2024-2025. To begin, we’ve got examined these merchandise in various dimension runs, attended plus-size attire panel shows, interviewed the plus-size base layer designers, and are assured in our conclusions.

Whereas she groups up with many gear testers, Tilton places items to the grindstone between keyboard blocks. Up to now in 2024, Tilton has packed in 62 days and 216 hours of testing girls’s base layers. From January to December 2023, Tilton examined girls’s base layers throughout 68 days and 198 hours of recreation. Her outings passed off within the frontcountry and backcountry together with bebopping by way of snowmobile. These days entailed blizzards, sub-zero temps, harsh wind, heavy and moist snow, loads of perspiration, and sunshine. That metric excludes working to get the mail (with base layers on underneath denims) and the extreme each day shoveling duties at her residence in Crested Butte, when she typically pulls on bibs.

One in all our testers is environmental journalist Kylie Mohr, who spends time working and snowboarding up and down the mountains of Montana in numerous blustery circumstances.

She checks girls’s base layers all through all of her adventures and delivers educated reviews on what she does and doesn’t like.

Testing Metrics

All through our subject checks and private expertise, we decide essentially the most aggressive girls’s base layers based mostly on a wide range of metrics together with high quality, consolation, match, longevity, and worth. We take a detailed take a look at every product’s heat, breathability, wicking and drying functionality, materials, elasticity, stretch, weight, density, seams, hems, lower, hand really feel, and elegance.

We additionally think about essentially the most revolutionary, sustainable, legacy, award-winning, and well-liked designs on the shelf as we speak. Arms down, these girls’s base layers serve a variety of athletes, purposes, and budgets.

Purchaser’s Information: The best way to Select the Greatest Ladies’s Base Layers

In our information, we deal with the perfect choices for chilly climate and the winter season, which are sometimes long-sleeve tops and ankle-length bottoms.

Technically, girls’s base layers characteristic a spread of designs together with tank, long-sleeve, and short-sleeve tops, in addition to ankle-length or capri pants. Some tops characteristic a hood, partial zipper, or thumbholes. Others are tailor-made with a crew collar, mock neck, or turtleneck. Whereas most against-skin layers lack pockets, we’ve seen leggings popping up with a spacious aspect pocket, which is beneficial to stash a cellphone, particularly post-activity while you pull off your snow pants.

Two basic umbrellas will assist you resolve which girls’s base layers to purchase:

• You’ll wish to think about how chilly the local weather is the place you play exterior. The colder the zone, the extra you’ll wish to think about a wool-based mix, greater density cloth, and heavier cloth weight.
• The second variable is how energetic you’ll be whilst you’re sporting that attire. Throughout train, like shoveling or occurring a winter run, your physique is producing warmth that might necessitate a extra breathable, much less density, low-weight high and backside.

For those who plan on being bodily energetic in above-freezing however cool climate, we advocate an artificial mix. For those who’ll be rounding out winter days in a below-freezing local weather, wool may be your biggest companion for heat. Different elements can affect the perfect base layer selection together with your physique’s circulation, pores and skin sensitivity to fibers (like wool), and the layers you placed on high.

Layering System 

Your alarm goes off. Don’t snooze: It’s time to rise up and dressed for chilly climate enjoyable. Your layers will work in a tiered system:

• Base Layer: Subsequent to pores and skin to wick sweat
• Midlayer: Provides heat to retain physique temperature
• Outer Layer: Safety from the weather, repels precipitation, blocks wind; insulated outer layers enhance heat

First, put in your underwear and socks. They higher be wool or an artificial mix — not cotton. Your heat, dry dermis will thanks. Your base layers go on subsequent.

Base Layer

Add your base layer high, backside, or onesie. In case your bottoms are lengthy, be certain that they go over your socks. Until you want your socks on the surface of your bottoms — that’s private choice. In case your bottoms are mid-shin size, like some compressive efficiency choices, regulate your socks and cloth, so there aren’t any overlapping, uneven factors that might rub or chafe. 

Midlayer

Now, it’s time to slide in your midlayer high and backside, relying on the day’s exercise. 

Going snowboarding in bounds? Attain for a streamlined fleece that also permits full vary of movement. Hanging out on the campsite? Pull on a cumbersome deep-pile sherpa fleece.

Your exercise will dictate what applicable midlayers so as to add on the underside. Perhaps you’ll pull on a fleece or insulated puffy pants for additional heat under workwear trousers or snow bibs.  

Outer Layer

Headed to the backcountry? Put on a snug insulated jacket on the way in which to the trailhead then strip all the way down to your baselayer or midlayer to begin, given you’ll rapidly heat up from exertion within the chilly temps. Operating in a breeze on an in any other case heat afternoon? Go for a softshell with no insulation.

If we’re resort snowboarding in under freezing temps, and we run chilly, we’ll typically do that trio: an uninsulated ski shell over each a fleece and puffy jacket. Insulated jacket wearers will possible discover they don’t want all three. 

A super layering system is all about studying what works for you and what number of layers you have to keep heat and dry.

Material Blends

The material blends of ladies’s base layers embody wool, artificial, or a mix of the 2. Inside these materials, there are numerous densities from light-weight to midweight or heavyweight.

Wool

We love wool. It regulates temperature very well and gives heat when it’s damp or moist. It’s developed to be rather more comfy towards the pores and skin and resists odors like a champ. The heat to weight ratio is excessive, packing a punch in a reasonably mild package deal. It’s an excellent selection for low-intensity out of doors actions like ice fishing or spectating a hockey sport. Amongst our high base layer decisions is the Smartwool Ladies’s Basic Thermal Merino Base Layer Crew and Smartwool Ladies’s Basic Thermal Merino Base Layer Backside, a 100% merino wool assortment.

That stated, 100% merino wool tends to be much less stout than synthetics, wears holes extra rapidly, and may get dishevelled all through use. If in case you have delicate pores and skin, even the smoothest 100% merino wool may really feel a tad lower than cloud-like subsequent to the pores and skin. Wool will get heavier when it’s moist and doesn’t dry as quick as synthetics. Relying in your choice, exercise degree, and the climate circumstances, you may favor a wool mix or straight artificial supplies.

Wool can value greater than its counterparts. Past Merino-sourced wool, we’ve got examined base layers with wool from yaks, which was a premium thread, extraordinarily mushy, and tremendous insulating.

Artificial

A substitute for wool is an artificial cloth, which is usually a mix that features polyester plus elastane or spandex for rebound, type, and long-lasting use. Some artificial materials are proprietary to a model with therapies that improve their odor-fighting capability and moisture-wicking prowess — the qualities that happen naturally in wool.

Artificial blends don’t supply as a lot heat and total temperature regulation that wool gives. As a result of they don’t soak up as a lot moisture and so they dry quick, they’re an awesome selection for high-intensity actions that produce a variety of perspiration with out lengthy moments of standstill, like throughout a hunt, when a chill might set in.

These fibers can work very well for individuals with delicate pores and skin, particularly for train use and the bonus of better sturdiness, stretch, and elasticity. Additionally, synthetics sometimes value lower than wool. One in all our favourite artificial choices is the REI Co-op Light-weight Base Layer Tights Ladies’s Plus Sizes, at a whopping $40.

One disadvantage: Odor-intense days should not sometimes lined up nicely by this fiber in its bare type.

Wool-Artificial Mix

Many of us discover a truthful steadiness of managing warmth and chill, sweat absorption, and masking up odors in a design that weaves collectively each wool and artificial fibers. Including synthetics to blends can improve the power and total lifespan of wool attire.

One in all our all-time favorites for sporting from the skintrack to completely satisfied hour is the Le Bent Ladies’s Core Light-weight Crew Base Layer, which incorporates 5% elastane and maintains a pleasant form all through lengthy days.

Weight Class or Thermal Class: Light-weight, Midweight, Heavyweight

If you store for ladies’s base layers, the merchandise are categorized by three weight zones, which typically refers to how heavy or mild the layer is and feels. The burden class is influenced by the material density and thickness, which modifications the actions that layer is suitable with.

Right here, we listed the burden class in every merchandise Specs — underneath Thermal Class — which relies on our take a look at outcomes.

Weight class isn’t instantly correlated to heat. A light-weight pure-wool high can bounce again a ton of physique warmth. It will likely be simpler to maneuver in, much less dense, and extra breathable than a midweight or heavyweight wool design.

Whereas everybody’s circulation and preferences are completely different, right here’s a basic begin level for deciphering a weight class based mostly on exercise degree and out of doors temperature:

Sedentary:

• 25-32+ levels: Light-weight, wool
• 15-25 levels: Midweight, wool
• <15 levels: Heavyweight, wool

Lively:

• 25-32+ levels: Light-weight, artificial
• 15-25 levels: Light-weight, wool-synthetic
• <15 levels: Midweight, wool

Light-weight

For those who’re working hardpack snow trails, snowshoeing, skate snowboarding, or doing uphill ski exercises in 30-degree temps, a light-weight base layer high or backside ought to do the trick, so long as there’s no wind chill.

Light-weight layers dump warmth very well. These might be a superb piece for hotter spring laps on the ski resort. However sitting idle on raise rides in chilly temps sometimes requires a hotter midweight base layer. One in all our favourite light-weight synthetics is the Helly Hansen Ladies’s HH LIFA Lengthy-Sleeve Crew Base Layer, and a light-weight wool mix that’s tremendous mushy and versatile is the Le Bent Ladies’s Core Light-weight Crew Base Layer.

Midweight

Not too ethereal and never too stuffy, the midweight base layer is perfect for wintry days snowboarding and using on the resort. It’s a good selection for snowmobiling, when pulling the throttle can pack windchill at excessive speeds.

That stated, for intense heat-building actions like enormous ski or splitboard excursions or snowshoeing, a midweight layer could be an excessive amount of except the temps are colder, like 15 levels or much less.

Squarely midweight, we love the Smartwool Ladies’s Basic Thermal Merino Base Layer Crew and Smartwool Ladies’s Basic Thermal Merino Base Layer Backside as a well-rounded package for chilly or below-freezing temps and days on the ski resort.

Heavyweight

Once we’re speaking excessive temperatures — 15 levels with windchill to nicely under freezing — then your greatest wager is a heavy-set base layer, particularly for ski resort laps if you find yourself sedentary on the way in which up.

Different extra passive out of doors actions might embody ice fishing, crusing, looking, spectating occasions, hanging at base camp throughout a mountaineering expedition, or snowmobiling groomed trails, particularly if sightseeing stops are frequent.

We don’t at the moment have any cumbersome heavyweight choices in our information. Lots of our 100% wool midweight selects may be layered beneath a midlayer fleece and down jacket for tremendous chilly circumstances, and we favor that versatility. The Kari Traa Rose Half Zip Baselayer High and Kari Traa Rose Excessive Waisted Baselayer Pants really feel lean however are full of warmth. These are our go-to on a 0-degree day on the ski resort. We don’t normally like sporting these whereas we ski tour to keep away from an oven-effect.

Material Density

A normal unit for measuring cloth density is gsm (grams per sq. meter). The upper the gsm, the denser and hotter that textile might be. A fluid-feeling shirt could be as little as 50-100 gsm, whereas denim reaches into the 340-450 gsm vary.

Some girls’s base layers don’t weigh a lot however have a dense cloth or excessive gsm. Due to this fact, they swing a excessive warmth-to-weight ratio, resembling the Kari Traa Rose Excessive Waisted Baselayer Pants with 240 gsm. After testing, we related that legging as midweight, because of the comparatively low density but excessive warmth punch.

Somewhat than including gsm labels to our product evaluations right here, we shared the overall weight class — light-weight, midweight, and heavyweight — which is extra ubiquitously used throughout manufacturers. Our listed weight class relies on our take a look at outcomes. That stated, understanding the best way to interpret the density of a base layer is a really great tool.

Right here’s a broad rule of thumb for gsm:

• Ultralight base layers: >150 gsm
• Light-weight base layers: 150-195 gsm
• Midweight base layers: 195-250 gsm
• Heavyweight base layers: 250-320 gsm

You’ll wish to match your bodily exertion or circulation to the material density. For those who plan to do excessive cardio exercise, select a base layer design with a decrease density.

For those who plan to be extra sedentary — resembling ready in lengthy ski raise strains throughout a blizzard, ice fishing, watching a hockey sport, or working errands — go for a better gsm. The next cloth density can be a superb possibility for people who’ve poor circulation or are likely to get chilled throughout winter actions.

Breathability

Along with trapping warmth, it’s essential on your base layer to breathe nicely and effectively wick moisture. Freezing sweat will make you colder sooner. Usually, the lighter or much less dense a design is, the extra breathable it is going to be. Merino wool can be extra breathable than synthetics. Base layers may be made with a mix of supplies that place extra breathable textiles in high-heat zones.

Once we’re speaking about engineering, we will’t overlook concerning the Icebreaker 260 ZoneKnit Lengthy Sleeve Crewe Thermal High and Icebreaker 260 ZoneKnit Thermal Leggings, which has a breathable mesh-like merino wool layer in all of the essential locations — the decrease legs, behind the knees, throughout the again and higher glutes, underneath the arms — so sweat can’t damage the day. The Kari Traa Rose Half Zip Baselayer High makes use of a lighter density merino wool underneath the arms and alongside the edges, which feels extra breathable.

Generally, we discovered that the Smartwool Ladies’s Basic Thermal Merino Base Layer Crew is a heat winter layer that breathes fairly nicely. It’s our high choose for the useless of winter but in addition for alpine pursuits in fall and winter. The Voormi Ladies’s Baselayer Bottoms Full Size and Lengthy Sleeve Baselayer Crew additionally breathe quite nicely, and repel water, preserving us dry after sweaty ascents and snowmobile rips.

If you already know you’re going to be busting it uphill on a heat day within the springtime, search for a fair lighter and extra breathable layer. One thing just like the Helly Hansen Ladies’s HH LIFA Lengthy-sleeve Crew Base Layer or REI Co-op Light-weight Base Layer Tights Ladies’s Plus Sizes and Top might be a key a part of your layering system.

Odor Prevention

For those who’re packing minimally for multiday use, like a hut-to-hut ski, merino wool does wonders with hiding odors. Usually, artificial supplies don’t champion coating stench in addition to this pure fiber. Merino wool wicks sweat away out of your physique, permitting it to evaporate quite than sink into your garments. Wool fibers soak up almost twice as a lot water vapor as cotton and 30 instances as a lot as polyester. The construction of wool binds with odors, taking part in avoid micro organism. 

Whereas polyester — a main thread in synthetics — isn’t naturally odor-resistant, clothes may be handled to imitate a few of the similar advantages as wool. Silver-based compounds and triclosan and triclocarban therapies are poisonous to odor-causing micro organism, preserving the nose-pinch at bay. Consider, these therapies’ effectiveness might lower over time as a garment is washed. 

Solar Safety

Many base layers hidden beneath midlayers or outerwear jackets won’t ever see the sunshine of day. However others, particularly light-weight ones geared for year-round or springtime use, will. That’s the place solar safety is a pleasant added characteristic.

The REI Co-op Light-weight Base Layer Lengthy-Sleeve Crew High Ladies’s Plus Sizes boasts a UPF score of fifty+, as does the Le Bent Ladies’s Feathertop Ultralight Hooded Lengthy Sleeve Tee. However Le Bent’s design additionally provides a hood, so that you’re getting further safety of your ears, plus the again of the neck. The Le Bent Ladies’s Core Light-weight Crew Base Layer likewise sports activities a UV 50+ tag.

Sturdiness

Thermal layers are an funding, so it is sensible that you really want them to final. They’re additionally just one piece of an extended listing of substances that’s wanted to enterprise out within the winter.

Artificial layers are sometimes extra steadfast than wool however could cause extra hassle with retaining odors. Producers typically add artificial fibers to their wool attire to assist enhance the general timestamp. Wool is of course hotter and odor-fighting however tends to be extra fragile. You’ll wish to take care placing them on, in addition to the way you wash and dry them.

Arms down, essentially the most sturdy building of any of those base layers is that of the Voormi Ladies’s Baselayer Bottoms Full Size and Voormi Ladies’s Lengthy Sleeve Baselayer Crew. Within the model’s proprietary course of, in-house seamsters create their Twin Floor materials, a precision-blended wool expertise with a lean inside layer of nice micron-wool plus a portion of polyester and nylon. After a number of years of use, we don’t see holes surfacing in these layers any time quickly.

Consolation & Match

Most base layers supply a level of flexibility and are mushy or nonabrasive, which helps total consolation and match. However some base layers we’ve examined up to now have had a tighter compression match for optimum athletic efficiency. One of many tougher base layers to tug on is the Voormi Ladies’s Baselayer Bottoms Full Size and Voormi Ladies’s Lengthy Sleeve Baselayer Crew, particularly on the seams. Nonetheless, we love how robust and time-withstanding this design is. The subsequent most close-fitting design in our information is the Halfdays Hallie Midweight Merino Legging, however it does supply ample stretch, even alongside the seams.

Once we take a look at base layers, we’re searching for tops that present sufficient vary of movement throughout the chest and shoulders, in addition to when lunging or squatting. The seams must be easy or flat, and the gusset must be well-constructed, so we don’t really feel any jabs or expertise chafing. The development may be very easy throughout the Ortovox 185 Rock’N’Wool Brief Pants and Ortovox 185 Rock’N’Wool Lengthy Sleeve.

We care concerning the silhouette, as a result of we favor arms that no less than cowl our wrists and torso lengths that don’t enable the decrease again to be uncovered to the weather.

Pant Size 

Most base layer pants attain all the way down to your ankle however some capri kinds hit under the knee, close to the shin bone. We like a cropped size for straightforward layering with our socks and ski boots. The Ortovox 185 Rock’N’Wool Brief Pants attain the knee and get rid of the necessity to layer our pants over socks.

Bottoms that attain nearer to your toes are normally tapered and cushty, to allow them to be simply tucked in when vital. However there’s normally sufficient pliability within the cloth to slip your winter socks beneath, for those who favor. 

Onesie & Drop Seat

Generally a separate high and backside simply gained’t lower it. We’re serious about these best-of-the-season powder days the place a spot in base layer protection might result in snow the place the solar doesn’t shine. Base layers with a seamless connection are a uncommon, however more and more well-liked, possibility within the base layer lineup. They’re known as onesies or one-pieces that embody a high and a backside sewed collectively. Suppose moist fits and footie pajamas. 

Main the cost is the Wild Rye Olivia Onesie base layer. Wearers are handled with head-to-toe merino wool. A hood provides coziness, and enjoyable patterns like chunky yellow florals stand out towards your folks’ all-black arsenal. A half-zip helps regulate temperature on this heat, 230 gsm model.

The most effective characteristic on a onesie is a rear zip, or drop seat, for straightforward launch. The drop seat is a detachable bottom flap, normally with zippers that span hip to hip above your booty, to make utilizing the toilet simpler. Nobody likes having to get completely bare to reply nature’s name. Brr! Although we haven’t examined this one but, the Backcountry Airblaster Merino Ninja Go well with is one other onesie possibility in the marketplace.  

Hoods & Collars 

Hoods are pretty uncommon on base layer tops. In any case, what number of hoods do you actually wish to be sporting directly? Hoods can typically add bulk across the neck and head space, particularly in case your base layer, fleece, puffy, and shell all have one.

However a few of our favourite base layers rock a hood, just like the First Lite Kiln Hoody and the Le Bent Ladies’s Feathertop Ultralight Hooded Lengthy Sleeve Tee, which is great for spring mountaineering and sunny, heat ski excursions. It may be good to have a slender hood round your neck to layer underneath a helmet or hat, which might additional block the solar and wind. 

Sure base layers have a scoop neck whereas others have collars with a quarter- or half-zipper on the chest and décolletage. We like a mock turtleneck lower to totally shield our neck and chest with out the restriction of a full turtleneck. The Kari Traa Rose Half Zip Baselayer High combines a half-zip with a mock turtleneck.

Sleeve Cuffs & Thumbholes

On long-sleeve base layers, the cuff is a bit of cloth that demarcates the garment’s edge, on the wrist. It’s sewn on to assist stop fraying and enhance consolation. The lengths of base layer sleeves, in addition to the depth and elasticity of their cuffs can vastly differ. Longer sleeves can attain the knuckles, masking the backs of the fingers and palms. Others finish on the wrist, earlier than extending over the hand.

Thumbholes, also referred to as thumb loops, are technical slits in lengthy cuffs, which the thumbs can sit in. It’s like a seatbelt on a cocoon that helps to maintain your fingers and wrists heat. Including thumb loops helps the sleeve keep drawn throughout the hand. That means, the material gained’t bunch up while you pull in your outer jacket. The exact width and placement of the loop that goes round your thumb varies by model and design. A handful of thumbhole designs are easy elastic bands. However many thumbhole designs are created with a large piece of cloth and embody seams.

Generally, thumbholes may be tedious to slip into, cumbersome underneath ski gloves, or incompatible with a watch. Some ski jacket designs have built-in wrist gaiters with thumbholes, which leads a site visitors jam round your wrist — and at worst, poorer circulation — in case your base layer high additionally has thumbholes.

We particularly just like the thumbholes on the Black Diamond Ladies’s Resolution 150 Merino Baselayer Crew. They’re stretchy sufficient to be comfy whereas sporting them for back-to-back hours. The Wild Rye Olivia Onesie thumbholes embody a beefy cuff, so that they’re cozy to put on indoors however exterior, we pull them again to placed on gloves. We discovered the thumbholes of the Voormi Ladies’s Lengthy Sleeve Baselayer Crew to be too small and restrictive, vastly as a result of lack of stretch within the seams. The First Lite Kiln Hoody thumbholes are very easy to tug on and off, as are those on the Icebreaker 260 ZoneKnit Lengthy Sleeve Crewe Thermal High.

Sustainability 

In the case of sustainability, shopping for new gear isn’t as environmentally pleasant as having a closet swap with mates or discovering scores on the thrift retailer. However acutely aware customers can store with Mom Nature and humanity in thoughts.

Discovering sustainable base layers consists of recycled supplies, ethically sourced materials, and accountable manufacturing amenities like people who don’t dump dangerous toxins into close by waterways and pay their workers a livable wage. 

Licensed Supplies

Some girls’s base layers are licensed by Bluesign, a company that works to maintain chemical compounds out of the availability chain for the well being of people, wildlife, pure sources, and the earth. Permitted factories meet requirements for air pollution management and employee security. Merchandise attain these requirements partially or as a complete. The Helly Hansen Ladies’s HH LIFA Lengthy-sleeve Crew Base Layer is Bluesign-approved.

The Le Bent Ladies’s Feathertop Ultralight Hooded Lengthy Sleeve Tee characteristic Nuyarn fibers, which set a formidable benchmark: Accountable Wool Normal Licensed, Bluesign-certified, Oeko-Tex Normal 100, and the International Natural Textile Normal.

Equally, the REI Co-op Light-weight Base Layer Tights Ladies’s Plus Sizes and High is made in a Honest Commerce licensed manufacturing unit. That certification means the manufacturing unit meets protected working circumstances in addition to environmental protections and that the availability chain is clear. Ortovox provides two stamps to its Ortovox 185 Rock’N’Wool Brief Pants and Ortovox 185 Rock’N’Wool Lengthy Sleeve: validation from the Honest Put on Basis, for equitable working circumstances, and local weather impartial.

Responsibly Sourced or Recycled Supplies

We’ve seen the model Daehlie do nicely with materials sourcing for merchandise, deciding on fiber from fast-growing eucalyptus timber on a farm that’s licensed by the Forest Stewardship Council.

Utilizing textiles sourced from recycled supplies, resembling outdated plastics, is a method that firms cut back waste and demand for petroleum-based merchandise. Supplies may be partially or absolutely recycled, just like the recycled polyester within the Patagonia Capilene line. 

Smartwool argues that wool is an inherently accountable selection: It’s not plastic, and it breaks down in water and soil. The model’s wool is ZQ-certified by a New Zealand-based group that units requirements for animal welfare, social accountability, and environmental sustainability. You’ll see this wool within the Smartwool Ladies’s Basic Thermal Merino Base Layer Crew and Backside, in addition to all the model’s base layer choices. 

Value & Worth

Our favourite girls’s base layers run from $40 to $229. That features choices for the budget-conscious shopper and the athlete desirous to splurge on a technical textile.

Price range
