Like a lot of the Zpacks sleeping bag vary, it is available in 4 colours, particularly inexperienced, blue, black, and my favourite orange. It is available in two widths, the usual, and the broad. On this evaluate, I examined the usual width and located it to be an ideal width that allowed me to maneuver round contained in the sleeping bag with out feeling cramped.

In the meanwhile it solely comes within the 10F and 20F temperature scores. I used and examined the 10F for this evaluate however the data introduced may even be related to the 20F model.

A number of options set this other than a lot of the different ultralight sleeping baggage and quilts available on the market.

Firstly, it has a full zip that enables the bag to be fully unzipped and used as a quilt.

Secondly, it’s overstuffed by 30% further 900 loft water resistant down. I like this characteristic. It means that you can use the bag extra occasions than most different baggage earlier than it must be washed. Excellent for the long-distance thru-hiker.

Thirdly, Zpacks has been capable of produce a high quality sleeping bag that’s heat, ultralight, and has best-in-class versatility.

When in comparison with different ultralight sleeping baggage, the full-length zip elevated the burden of this mummy sleeping bag barely. Nevertheless, the flexibility to make use of the bag in a extra diversified vary of temperatures and conditions appears to be an excellent compromise.

The anti-snag zip labored properly due to a strip of webbing that runs the size of the zip, and the draft collar does an honest job of stopping drafts from getting into.

The Zpacks Mummy Sleeping Bag comes with an outsized Dyneema stuff sack. Not solely is the stuff sack waterproof however the massive dimension makes it straightforward to pack up the bag within the morning. Though the employees sack is kind of massive, it may be compressed fairly a bit by sitting on the stuff sack to push the surplus air out of the stuff sack. I used to be capable of scale back the pack dimension by half when utilizing this method.

General, the model new Zpacks Mummy Sleeping Bag is the most effective full zip mummy sleeping bag for 2024. The flexibility of this mummy bag permits it for use as a backpacking quilt and is certain to be very fashionable on thru-hiking trails around the globe in 2024 and past.

Down kind / fill energy

The Zpacks Mummy sleeping bag is filled with 900-fill energy goose down. They use water resistant PFC-FREE DownTek which lets you use the sleeping bag in damp environments with a bit of extra confidence. That is proper up there with a few of the highest quality down used on any sleeping bag in the meanwhile, only a few are utilizing a better loft than 900 fill energy.

What makes this sleeping bag higher than a lot of the competitors is the overstuffing of the baffles. With 30% further down within the baffles it permits the bag to do a greater job at staying lofted in tough conditions corresponding to damp climate, or when your bag could be very properly used corresponding to on a thru-hike.

When your bag is soiled, soaked with weeks and months of sunscreen, physique oils, and extra it’ll lose plenty of its loft and never be as efficient at preserving you heat. The additional 30% of fill will guarantee most loft when different baggage are beginning to lose their loft. Through-hikers who may use this bag for 100-150 nights earlier than washing it’ll love this characteristic.

Building

Let’s take an in-depth have a look at how the Zpacks Mummy Sleeping Baggage are made with options such because the Interior and Outer Shell materials, zippers, baffles, draft tubes, hood, and climate resistance.

Outer and Interior Shell material

The exterior face material and inner liner of the Zpacks Hooded Mummy Sleeping Baggage are made utilizing a 7 Denier Ripstop Ventum Nylon. This is likely one of the lightest materials used on any sleeping bag which you could purchase in 2024.

It’s coated with a PFC-free DWR coating to forestall drops of water from getting into the bag. Whenever you check out this material it’s nearly see-through and very light-weight.

Climate resistance

As talked about above, there’s a PFC-free DWR coating on the sleeping bag material. I examined the water resistance and high quality of the DWR coating. Whereas I didn’t sleep exterior in rain I poured a number of liters of water on the sleeping bag, and I can affirm it’ll present an honest degree of water resistance.

The Zpacks Mummy Sleeping Bag could be ok to sleep exterior below the celebs when there’s a very small quantity of condensation in a single day. As talked about above, the 30% overstuffing of down will help in preserving it as lofted as doable.

As you’ll be able to see from the photograph beneath once I examined the DWR coating on the material, the water beaded fairly properly. It’s going to get in by the stitching and the place the zips are however it’s reassuring to know that Zpacks use water resistant down. This down would solely have the ability to take in about 20% of the water. Very spectacular.

Disclaimer: I don’t advocate that you just pour a number of bottles of water over your sleeping bag to check its water resistance nor sleep exterior within the rain!

Baffles

Zpacks use a mix of vertical and horizontal baffles.

The vertical baffles are used on the higher a part of the bag that corresponds along with your higher physique. They do an excellent job of stopping any down from shifting throughout the night time. In case you are a aspect sleeper or transfer round so much throughout the night time, which means this design will work properly for you.

The decrease part makes use of horizontal baffles. These types of baffles do an excellent job of locking in as a lot warmth as doable. The horizontal baffles at your toes aren’t sewn by to maximise the loft and heat to your toes. Should you endure from chilly toes then you’ll like this design.

Should you endure from actually chilly toes Zpacks have you ever coated with their Goose Down Socks.

General, there may be little to criticize and much to reward with the baffle design, which mixed with the overstuffing of every baffle results in me regard this sleeping bag among the many better of the most effective.

Zips and Draft Tube

The Zpacks Mummy Sleeping Bag is the most recent addition to the Zpacks sleeping bag vary because it was solely launched in early 2023.

The zips and draft tubes work as anticipated and do an excellent job.

Alongside the zip, there’s a size of inner webbing that’s each light-weight and enough sufficient to forestall most snags. Should you strive onerous sufficient you’ll snag the zip however in most conditions, it really works properly.

Alongside the size of the zip, there’s a draft tube which does an excellent job. There isn’t a draft tube across the collar or the hood like many different sleeping baggage. However the bag nonetheless appears to do an sufficient job of preserving the heat in.

Hood

The hood on the Zpacks Mummy Bag could be very fundamental in design and performance. There isn’t a draft tube across the hood or collar however the fundamental design appears to do an excellent job of preserving the warmth in.

The scale of the hood are beneficiant sufficient to have the ability to put on a beanie, down balaclava, or expedition-weight down jacket with out subject.

The toggles are light-weight and fundamental however work properly. When sleeping in your aspect, abdomen, or again the hood stays in place and performs properly.

General, the hood is not so good as another sleeping baggage however the hood is heat and the fundamental design does the job of preserving the general weight of the sleeping bag as mild as doable.

Stuff Sack

The Zpacks Mummy Sleeping Bag makes use of an impressively light-weight Dyneema stuff sack. It’s waterproof and fairly massive. Having a big stuff sack makes it straightforward to pack the bag within the morning. No must attempt to squeeze it in completely each time. Simply shove it in any method you want and it’ll work.

The stuff sack doesn’t use compression straps. You possibly can sit on the stuff sack after placing the sleeping bag inside. It will take away the air and can lower the dimensions of the packed-up sleeping bag to about half its dimension. After sitting on the bag, do up the clips, and it’ll pack to a small dimension.

The photograph beneath doesn’t do justice to simply how small the 10F sleeping bag can compress. It may possibly go smaller than the photograph beneath! Nice for the times whenever you want all of the room doable inside your ultralight backpack.

Consolation

The Zpacks Mummy Sleeping Baggage are available three lengths and two widths. The widths are beneficiant and enough for most individuals to not really feel too cramped. I examined the usual width and located it good for my physique dimension, even when carrying an expedition spec down jacket. In case you are a bigger construct or need further room, you’ll be able to take into account the broader width. Examine the web site for the precise specs.

General, the sizing of the bag is nice and precisely as talked about on the specification sheet on their web site.

Heat

Zpacks don’t check their baggage to EN or the newer ISO 23537 Requirements. They use temperature scores primarily based on their very own expertise. They estimate the temperature scores to be near the ISO Rated ‘Restrict’ Score of a Sleeping Bag, which is typically referred to as the ‘transition’ ranking.

I examined this sleeping bag in temperatures just under freezing and I stayed heat. As but I’ve not examined the sleeping bag in temperatures as little as 10F. However judging from the quantity of down used within the bag, mixed with the 900 loft, and the standard of the baffles, I’d consider that the 10F and 20F scores ought to be fairly near the restrict/transition scores for most individuals.

Caring in your Zpacks Mummy Sleeping Bag

The Zpacks Mummy Sleeping Bag will not be the most cost effective sleeping bag available on the market, so it’s price caring for it. Among the finest issues you are able to do is put on clear backpacking base layers to mattress to forestall sweat, grime, and physique oil from penetrating the liner of the sleeping bag. It’s also possible to use a sleeping bag liner to maintain it clear.

The way to retailer your Zpacks Mummy sleeping bag

Zpacks don’t present a lofting bag, which is one factor that could possibly be improved. When storing your Zpacks sleeping bag it’s best to not go away it compressed contained in the stuff sack. Prolonged intervals of doing this could have an effect on the lofting capability of the down. The upper the standard of the down (the upper the loft quantity, eg 900) the extra likelihood it’s important to injury the down over an prolonged interval.

I strongly advocate storing your sleeping bag in a bigger lofting bag to extend the size of service of your bag. Should you do that, you’re going to get at the least 10-20 good years of use out of this bag. Particularly in case you handle it and wash it when wanted.

The way to wash your Zpacks Mummy Sleeping Bag

Over time the Zpacks Mummy sleeping bag will lose a little bit of its loft and you might begin to complain that the bag is not so good as it was. This occurs with each down sleeping bag. The overstuffing of down on this bag will imply it’ll outlast most different baggage which might be used equally.

Perhaps your bag may begin to have some funky smells that appear to be a cross between a sweaty gymnasium towel and an unwashed homeless particular person. If this happens it’s time to give the Zpacks sleeping bag a wash.

Worth

On the time of reviewing this product, the brand new Zpacks Mummy Sleeping Bag is priced on the larger finish of the market. There are cheaper choices on the market however in case you are in search of one sleeping bag to make use of in an awesome number of temperatures then this could possibly be the one you might have been in search of.

With the ability to fully unzip the bag and use it as a quilt in hotter climate eliminated the necessity to buy a number of sleeping baggage. And when it does get chilly, zip up the sleeping bag, cinch the hood tight and you’ll be good and heat.

And in contrast to another sleeping baggage, there don’t look like any provide chain points.

Zpacks Mummy Sleeping Baggage Vs The Relaxation

How do the all-new Zpacks Mummy Sleeping Baggage evaluate to different Ultralight Sleeping Baggage and Backpacking Quilts in 2024?

In comparison with the Therm-a-Relaxation Hyperion Sleeping Bag Vary, the Zpacks Bag is heavier. However there may be far more room contained in the bag and the flexibility to fully unzip the bag and use it as a quilt.

In comparison with the New Zealand Model Macpac Dragonfly Sleeping Bag Sleeping Bag, the Zpacks are lighter and far more versatile.
