The Therm-a-Relaxation Hyperion was first launched within the Spring of 2019. The ultralight Therm-a-Relaxation Hyperion Sleeping Bag vary turned a hit as they chased the ultralight sleeping bag market. As soon as upon a time, ultralight backpackers and thru-hikers had 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 needs the lightest doable sleeping bag with the very best doable high quality.
Therm-a-Relaxation has seen no must make any modifications since that point as it’s nonetheless the most effective ultralight sleeping luggage in the marketplace.
The temperatures of the luggage had been independently examined to EN/ISO requirements. The sleeping bag normal, ISO 23537, was launched as the brand new sleeping bag normal. The temperature rankings on the Hyperion sleeping luggage had been examined to this normal. I like this dedication to making sure the sleeping bag rankings are independently examined reasonably than a greatest guess on how heat you have to be like some corporations do. Extra on the temperature rankings slightly later.
Down sort/fill energy
The Therm-a-Relaxation Hyperion Sleeping Luggage are full of 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 additionally has good water resistance qualities because it makes use of Nikwax water repellent down. This implies if you’re unlucky sufficient to search out your self in very dangerous climate and your sleeping bag will get moist, it won’t soak up as a lot water as different sleeping luggage and nonetheless have the ability to loft and hold you heat.
Building
Let’s check out how the Therm-a-Relaxation Hyperion Sleeping Luggage 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 virtually all trendy ultralight sleeping luggage, the material is mild and virtually see-through, particularly while you maintain it as much as the sunshine.
When testing the Therm-a-Relaxation Hyperion Sleeping Luggage 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 Luggage use the identical 10 Denier material that’s used on the outer shell minus the DWR coating. It isn’t solely ultralight but additionally resistant to ripping.
I did the rip check on the material through the use of my arms to try 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 lower 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 affirm it’ll present an honest degree of water resistance that’s a minimum of 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 exterior beneath the celebs when condensation comes down in a single day.
Disclaimer:I don’t suggest that you just pour an entire bottle of water over your sleeping bag to check its water resistance. I do the testing so you recognize simply how good or dangerous this product is.

Baffles
The Hyperion Sleeping luggage use a system of baffles which can be slightly completely different from different sleeping luggage in the marketplace. Whereas the field baffles aren’t any completely 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 principle, this technique is nice. However there may be one problem. What occurs while you roll over at night time? Solely 30% of the insulation is on the underside. Nicely, if this happens you’ll not keep as heat. To fight this, the Hyperion Sleeping Luggage have a strap system that they wish to name, SynergyLink Connectors that join the sleeping bag to the sleeping pad and forestall this from occurring.
When testing this technique I discovered it to work surprisingly effectively. Anybody who has used an ultralight backpacking quilt might be accustomed to such a system, however sleeping bag homeowners aren’t so accustomed to such a system. The sleeping bag stayed in place effectively sufficient for me to roll round within the bag and never induce the underside facet of the bag with much less down to maneuver to the highest. Whereas facet sleeping the bag turned simply sufficient for me to be very snug and never have the hood cowl my mouth.
Like most ultralight sleeping luggage, I’d have appreciated every baffle to be full of 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 would have to be performed once in a while to maintain the bag acting at its greatest.

Zips and Draft Tube
The Hyperion sleeping bag collection encompasses a 1/2-length zip and a draft tube.
I attempted my greatest to destroy the zip and tried to snag it on the inner draft collar. I used to be capable of snag the zip after I tried however for most individuals, there may be nothing to fret about. There’s a little bit of a studying curve with regards 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 decent match and is fiddly to shut. After just a few makes an attempt, it isn’t a problem, and after just one night time of use, it’s simple sufficient to make use of.
Total, the zips and draft tubes do an excellent job and there may be not a lot that may be faulted. Nonetheless, because of the tight inner dimensions of the Hyperion sleeping luggage, I discovered it may very well be a problem to zip up the bag with out guaranteeing I used to be tucked inside completely. With follow, it turned simpler.

Hood
The hood on the Hyperion Sleeping Bag is sweet and encompasses a full collar the entire manner round. It’s a very tight match and in contrast to many different sleeping luggage, it won’t be doable to sleep together 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 exterior the hood. This isn’t an enormous problem however one thing you have to pay attention to. That very same compact measurement of the hood ensures there aren’t many air pockets that take power to warmth, power 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 may very well be slightly greater 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 results 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 a whole lot of time sleeping on my facet and rolling over rather a lot. The hood labored completely and was capable of 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, perhaps a bit extra overfill within the hood and draft collars can be an excellent enchancment. And I barely bigger match can be good. However as that is such a distinct segment ultralight bag I’m not positive that’s one thing that Therm-a-Relaxation will ever do as it might solely add extra weight to the bag.
Stuff Sack
The usual Stuff Sack provided with the Hyperion Sleeping Luggage is sweet and there’s no want for anybody to think about upgrading to anything. It’s light-weight and might be compressed with the facet straps to compress the luggage into a really small measurement of round 2.5L. The Hyperion is essentially the most compressible sleeping bag in its class of ultralight sleeping luggage. Others could come shut however that is the very best, 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 measurement. Confer with the Specification chart for detailed comparisons.
Packability
The Therm-a-Relaxation Hyperion Sleeping Luggage are essentially 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 measurement.

Consolation
The interior sizing of the Therm-a-Relaxation Hyperion Sleeping Luggage is kind of small. There’s not a whole lot of room to maneuver round inside in comparison with different ultralight sleeping luggage. There are execs and cons of tight mummy-style sleeping bag sizing.
Though the Hyperion fashions are basic mummy-style sleeping luggage, they’ve very compact inner dimensions. Their inner dimension is among the smallest of their class. These compact inner dimensions permit for a larger capacity to maintain you heat as you waste much less power 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 constructive while you need an ultralight sleeping bag.
The tight inner dimensions have some unfavorable points that have to be highlighted. If you wish to put on a winter-grade down jacket whilst you sleep it’ll make for a decent match. This could be a draw back if you wish to prolong the temperature vary of the luggage throughout the shoulder seasons. Having stated that, they are going to match an insulated sleeping bag liner with out problem, in order that is perhaps a greater possibility for shoulder season journey. In the event you get chilly toes, you might 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 an excellent 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 facet it was surprisingly good. I believed it would trigger a problem nevertheless it didn’t.
After I slept on my again, which I are likely to do once in a while, I discovered myself caught contained in the hood. That is my solely criticism of this bag simply pay attention to this. A abdomen sleeper can have a problem with this bag. Having stated that, most individuals hardly ever sleep of their abdomen, so for most individuals, the compact measurement and ultralight weight might be value it.
Total, the Therm-a-Relaxation Hyperion Sleeping Luggage are tight-fitting sleeping luggage attributable to their inner dimensions. If you’re chubby, 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 may very well be the proper ultralight sleeping bag for you.
