The Therm-a-Relaxation Hyperion was first launched within the Spring of 2019. The ultralight Therm-a-Relaxation Hyperion Sleeping Bag vary grew to become a hit as they chased the ultralight sleeping bag market. As soon as upon a time, ultralight backpackers and thru-hikers have been seen as freaks who compromised sturdiness and security whereas chasing decrease ounces and grams. Now ultralight is mainstream and accessible to all. The Hyperion vary is unashamedly focused on the backpacker who desires the lightest potential sleeping bag with the best potential high quality.
Therm-a-Relaxation has seen no must make any adjustments since that point as it’s nonetheless probably the greatest ultralight sleeping luggage in the marketplace.
The temperatures of the baggage have been independently examined to EN/ISO requirements. The sleeping bag customary, ISO 23537, was launched as the brand new sleeping bag customary. The temperature scores on the Hyperion sleeping luggage have been examined to this customary. I like this dedication to making sure the sleeping bag scores are independently examined slightly than a finest guess on how heat you ought to be like some firms do. Extra on the temperature scores just a little later.
Down sort/fill energy
The Therm-a-Relaxation Hyperion Sleeping Baggage are crammed with 900+ loft Hyperdry Goose Down in 2024. That is the top-of-the-range down used on any Therm-a-Relaxation Sleeping Bag. It isn’t solely ultra-lightweight but in addition has good water resistance qualities because it makes use of Nikwax water repellent down. This implies in case you are unlucky sufficient to search out your self in very unhealthy climate and your sleeping bag will get moist, it won’t soak up as a lot water as different sleeping luggage and nonetheless be capable of loft and maintain you heat.
Building
Let’s check out how the Therm-a-Relaxation Hyperion Sleeping Baggage are made with options such because the Interior and Outer Shell materials, zippers, baffles, draft tubes, hood, and climate resistance.
Outer Shell material
The exterior face material of the Therm-a-Relaxation Hyperion Sleeping Bag is made utilizing a 10-Denier Ripstop Nylon which is coated with a DWR coating to stop drops of water from getting into the bag. Like nearly all trendy ultralight sleeping luggage, the material is mild and nearly see-through, particularly whenever you maintain it as much as the sunshine.
When testing the Therm-a-Relaxation Hyperion Sleeping Baggage I poured a big quantity of water on the outer material to check the water resistance of the material and the water beaded properly and ran off the material. Extra on that later.
Interior material
The Therm-a-Relaxation Hyperion Sleeping Baggage use the identical 10 Denier material that’s used on the outer shell minus the DWR coating. It isn’t solely ultralight but in addition resistant to ripping.
I did the rip take a look at on the material by utilizing my palms to attempt to rip the material, even across the stitching space. I used to be unable to tear it. With a pointy object or knife, I may minimize the material simply however I don’t need to deliberately destroy this superior sleeping bag.
Climate resistance
As talked about above, I did drop fairly a little bit of water on the outer face material to check the water repellency and high quality of the DWR coating. I can verify it should present a good degree of water resistance that’s at the least equal to or higher than all of the competitors within the Ultralight Sleeping Bag market.
The Therm-a-Relaxation Hyperion Sleeping Bag is sweet sufficient to sleep outdoors below the celebs when condensation comes down in a single day.
Disclaimer:I don’t suggest that you simply pour an entire bottle of water over your sleeping bag to check its water resistance. I do the testing so you already know simply how good or unhealthy this product is.

Baffles
The Hyperion Sleeping luggage use a system of baffles which might be just a little totally different from different sleeping luggage in the marketplace. Whereas the field baffles aren’t any totally different from many different sleeping luggage, they stuff 70% of the down into the highest layer and 30% within the backside layer. What meaning is the layer that’s going through down onto the sleeping pad has much less insulation and the highest layer does all of the work of maintaining you heat.
In concept, this method is nice. However there’s one problem. What occurs whenever you roll over at night time? Solely 30% of the insulation is on the underside. Properly, if this happens you’ll not keep as heat. To fight this, the Hyperion Sleeping Baggage have a strap system that they prefer to name, SynergyLink Connectors that join the sleeping bag to the sleeping pad and forestall this from occurring.
When testing this method I discovered it to work surprisingly effectively. Anybody who has used an ultralight backpacking quilt will probably be acquainted with such a system, however sleeping bag homeowners are usually not so acquainted with such a system. The sleeping bag stayed in place effectively sufficient for me to roll round within the bag and never induce the underside aspect of the bag with much less down to maneuver to the highest. Whereas aspect sleeping the bag turned simply sufficient for me to be very comfy and never have the hood cowl my mouth.
Like most ultralight sleeping luggage, I might have appreciated every baffle to be filled with barely extra down. Not like an overfill, however sufficient to scale back clumping of the down which occurs over time and is a sign that the sleeping bag wants a wash. It’ll should be completed once in a while to maintain the bag acting at its finest.

Zips and Draft Tube
The Hyperion sleeping bag sequence encompasses a 1/2-length zip and a draft tube.
I attempted my finest to destroy the zip and tried to snag it on the interior draft collar. I used to be in a position to snag the zip once I tried however for most individuals, there’s nothing to fret about. There’s a little bit of a studying curve relating to utilizing the zip and locking it in place with the press stud subsequent to the hood. After I say that, the bag is a good match and is fiddly to shut. After a number of makes an attempt, it isn’t a problem, and after just one night time of use, it’s simple sufficient to make use of.
General, the zips and draft tubes do job and there’s not a lot that may be faulted. Nonetheless, because of the tight inside dimensions of the Hyperion sleeping luggage, I discovered it might be a problem to zip up the bag with out guaranteeing I used to be tucked inside completely. With apply, it grew to become simpler.

Hood
The hood on the Hyperion Sleeping Bag is sweet and encompasses a full collar the entire approach round. It’s a very tight match and in contrast to many different sleeping luggage, it won’t be potential to sleep along with your backpacking pillow contained in the hood. The hood is simply too tight a match for that. In the event you use a backpacking pillow it should be outdoors the hood. This isn’t a giant problem however one thing you need to concentrate on. That very same compact dimension of the hood ensures there are usually not many air pockets that take vitality to warmth, vitality that’s higher spent maintaining you heat.
The Drawcords and toggles used to cinch the hood closed all work as anticipated and won’t be a problem for customers.
The neck and hood collars might be just a little larger and will have extra overfilled for higher warmth retention. In my expertise the hood collar and neck collar areas of sleeping luggage are the primary locations to get soiled from physique oils and sweat which ends up in the down changing into extra compressed and clumped, making them much less environment friendly at maintaining you heat.
After I examined the Therm-a-Relaxation Hyperion Sleeping Bag I spent numerous time sleeping on my aspect and rolling over lots. The hood labored completely and was in a position to transfer with me as I turned, even when utilizing the straps to carry the sleeping bag onto the ultralight sleeping pad. I used the Therm-a-Relaxation Uberlite sleeping pad when testing this sleeping bag. I may discover no higher ultralight sleeping system than this.
As talked about above, possibly a bit extra overfill within the hood and draft collars can be enchancment. And I barely bigger match can be good. However as that is such a distinct segment ultralight bag I’m not certain that’s one thing that Therm-a-Relaxation will ever do as it may solely add extra weight to the bag.
Stuff Sack
The usual Stuff Sack equipped with the Hyperion Sleeping Baggage is sweet and there’s no want for anybody to contemplate upgrading to the rest. It’s light-weight and may be compressed with the aspect straps to compress the baggage into a really small dimension of round 2.5L. The Hyperion is probably the most compressible sleeping bag in its class of ultralight sleeping luggage. Others could come shut however that is the most effective, solely ultralight hoodless sleeping luggage or backpacking quilts are extra compact.
Compression
As talked about above the stuff sac will compress the bag to a smaller dimension. Seek advice from the Specification chart for detailed comparisons.
Packability
The Therm-a-Relaxation Hyperion Sleeping Baggage are probably the most packable of all of the ultralight sleeping luggage of their class. A mix of the excessive loft down, 10D material, and compact zip all contribute to the small pack dimension.

Consolation
The interior sizing of the Therm-a-Relaxation Hyperion Sleeping Baggage is kind of small. There’s not numerous room to maneuver round inside in comparison with different ultralight sleeping luggage. There are professionals and cons of tight mummy-style sleeping bag sizing.
Though the Hyperion fashions are traditional mummy-style sleeping luggage, they’ve very compact inside dimensions. Their inside dimension is among the smallest of their class. These compact inside dimensions enable for a larger skill to maintain you heat as you waste much less vitality maintaining air pockets heat. Consequently, Therm-a-Relaxation can add much less down into the bag and use much less material in a lighter bag. All of this can be a optimistic whenever you need an ultralight sleeping bag.
The tight inside dimensions have some unfavourable elements that should be highlighted. If you wish to put on a winter-grade down jacket whilst you sleep it should make for a good match. This generally is a draw back if you wish to lengthen the temperature vary of the baggage through the shoulder seasons. Having mentioned that, they’ll match an insulated sleeping bag liner with out problem, in order that is likely to be a greater choice for shoulder season journey. In the event you get chilly toes, you may put on a pair of down booties contained in the sleeping bag to remain heat.
After I examined the sleeping bag I discovered that the SynergyLink Connectors did job of maintaining the sleeping bag going through up. When sleeping on my again the Hyperion Bag was nice, excellent. After I rolled over and slept on my aspect it was surprisingly good. I believed it’d trigger a problem but it surely didn’t.
After I slept on my again, which I are inclined to do once in a while, I discovered myself caught contained in the hood. That is my solely criticism of this bag simply concentrate on this. A abdomen sleeper could have a problem with this bag. Having mentioned that, most individuals hardly ever sleep of their abdomen, so for most individuals, the compact dimension and ultralight weight will probably be price it.
General, the Therm-a-Relaxation Hyperion Sleeping Baggage are tight-fitting sleeping luggage because of their inside dimensions. If you’re obese, look elsewhere, this bag won’t be just right for you. If you’re of common construct this might be just right for you. If you’re a small construct, this might be the right ultralight sleeping bag for you.
