This is a gear assessment concerning the Therm-a-Rest Hyperion Sleeping Bags in 2022. The sleeping bag assessment covers the entire Therm-a-Rest Hyperion Sleeping Bag Range however I’ve centered on the Therm-a-Rest Hyperion 20F/-6C which I’ve extensively examined and reviewed.
When it involves ultralight sleeping luggage the Therm-a-Rest Hyperion vary has been the king since its introduction within the spring of 2019. But must you purchase it? I’ve spent over 2500 nights sleeping in sleeping luggage over time and have examined many luggage over time, together with the Hyperion from Therm-a-Rest. So this in-depth assessment will let whether it is for you.
All the Therm-a-Rest Hyperion Sleeping Bags use high-quality 900+ Nikwax Hydrophobic down, ultralight 10D material on the internal and outer shell, with the outer material coated with a DWR.

Therm-a-Rest Hyperion Ultralight Sleeping Bags
The Therm-a-Rest Hyperion was first launched within the Spring of 2019. The ultralight Therm-a-Rest Hyperion Sleeping Bag vary grew to become a hit as they chased the ultralight sleeping bag market. Once 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. And the Hyperion vary is unashamedly focused on the backpacker who desires the lightest potential sleeping bag with the very best potential high quality.
Therm-a-Rest has seen no have to make any adjustments since that point as it’s nonetheless among the finest ultralight sleeping luggage available on the market.
The temperatures of the luggage have been independently examined to EN/ISO requirements. The sleeping bag commonplace, ISO 23537, was launched as the brand new sleeping bag commonplace. The temperature scores on the Hyperion sleeping luggage have been examined to this commonplace. Personally, I like this dedication to making sure the sleeping bag scores are independently examined reasonably than a greatest guess on how heat you have to be like some corporations do. More on the temperature scores a bit later.
Down kind/fill energy
The Therm-a-Rest Hyperion Sleeping Bags are crammed with 900+ loft Hyperdry Goose Down in 2022. This is the top-of-the-range down used on any Therm-a-Rest Sleeping Bag. It shouldn’t be solely ultra-lightweight but additionally has good water resistance qualities as they use Nikwax water repellent down. This means if you’re unlucky sufficient to seek out your self in very dangerous climate and your sleeping bag will get moist, it is not going to take up as a lot water as different sleeping luggage and nonetheless be capable to loft and preserve you heat.
Construction
Let’s check out how the Therm-a-Rest Hyperion Sleeping Bags are made with the options such because the Inner and Outer Shell materials, zippers, baffles, draft tubes, hood, and climate resistance.
Outer Shell material
The exterior face material of the Therm-a-Rest Hyperion Sleeping Bag is made utilizing a 10-Denier Ripstop Nylon which is coated with a DWR coating to stop drops of water from coming into the bag. Like virtually all trendy ultralight sleeping luggage, the material gentle and virtually see-through, particularly whenever you maintain it as much as the sunshine.
When testing the Therm-a-Rest Hyperion Sleeping Bags 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. More on that later.
Inner material
The Therm-a-Rest Hyperion Sleeping Bags use the identical 10 Denier material that’s used on the outer shell minus the DWR coating. It shouldn’t be solely ultralight but additionally resistant to ripping.
I did the rip take a look at on the material through the use of my fingers 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 wish to deliberately destroy this superior sleeping bag.
Weather 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 can present a good stage 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-Rest 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 a complete bottle of water over your sleeping bag to check its water resistance. I do the testing so simply how good or dangerous this product is.
Baffles
The Hyperion Sleeping luggage use a system of baffles which are a bit totally different from different sleeping luggage available on the market. While the field baffles are not 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 which means 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 protecting you heat.
In concept, this technique is nice. But there’s one situation. What occurs whenever you roll over at evening the 70% of the insulation is on the underside? Well, if this happens you’ll not keep as heat. To fight this, the Hyperion Sleeping Bags 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 properly. Anyone who has used an ultralight backpacking quilt shall be accustomed to such a system, however sleeping bag house owners are usually not so accustomed to such a system. The sleeping bag stayed in place properly 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. While 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’d have preferred every baffle to be full of barely extra down. Not like an overfill, however sufficient to cut back clumping of the down which occurs over time and is a sign that the sleeping bag is in want of a wash. In truth, it can must be achieved every now and then to maintain the bag acting at its greatest.
The SynergyLink Connectors preserve the Therm-a-Rest Hyperion Sleeping Bag in place.
Zips and Draft Tube
The Hyperion sleeping bag collection contains 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 in a position to snag the zip once I tried however for most individuals, there’s nothing to fret about. There is a little bit of a studying curve on the subject of utilizing the zip and locking it in place with the press stud subsequent to the hood. When 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 evening of use, it’s straightforward sufficient to make use of.
Overall, the zips and draft tubes do a great job and there’s not a lot that may be faulted. But because of the tight inner dimensions of the Hyperion sleeping luggage, I discovered it could possibly be a problem to zip up the bag with out making certain I used to be tucked inside completely. With apply, it grew to become simpler.
Hood
The hood on the Hyperion is sweet and contains a full collar the entire approach round. It is a really tight match and in contrast to many different sleeping luggage, it is not going to be potential to sleep together with your backpacking pillow contained in the hood. The hood is simply too tight a match for that. If you employ a backpacking pillow it should be exterior the hood. This shouldn’t be a giant situation however one thing you should concentrate on. That similar compact measurement of the hood ensures there are usually not many air pockets that take vitality to warmth, vitality that’s higher spent protecting 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 could possibly be a bit 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 results in the down turning into extra compressed and clumped, making them much less environment friendly at protecting you heat.
When I examined the Therm-a-Rest Hyperion Sleeping Bag I spent loads of time sleeping on my aspect and rolling over so much. 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-Rest 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 a great enchancment. And I barely bigger match can be good. But as that is such a distinct segment ultralight bag I’m not certain that’s one thing that Therm-a-Rest will ever do as it might solely add extra weight to the bag.
Stuff Sack
The commonplace Stuff Sack provided with the Hyperion Sleeping Bags is sweet and there’s no want for anybody to think about upgrading to anything. It is light-weight and might be compressed with the aspect straps to compress the luggage into a really small measurement of round 2.5L. In truth, the Hyperion is essentially the most compressible sleeping bag in its class of ultralight sleeping luggage. Others might 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. Refer to the Specification chart for detailed comparisons.
Packability
The Therm-a-Rest Hyperion Sleeping Bags are essentially the most packable of all of the ultralight sleeping luggage of their class. A mixture of the excessive loft down, 10D material, and compact zip all contribute to the small pack measurement.
Comfort
The inner sizing of the Therm-a-Rest Hyperion Sleeping Bags is on tight measurement. There shouldn’t be loads of room to maneuver round inside in comparison with different ultralight sleeping luggage. There are professionals and cons of tight mummy-style sleeping bag sizing.
Although the Hyperion fashions are basic mummy-style sleeping luggage, they’ve very compact inner dimensions. In truth, their inner dimension are one of many smallest of their class. These compact inner dimensions permit for a higher capability to maintain you heat as you waste much less vitality protecting air pockets heat. As a outcome, Therm-a-Rest can add much less down into the bag and use much less material in a lighter bag. All of it is a constructive whenever you need an ultralight sleeping bag.
The tight inner dimensions have some adverse elements that must be highlighted. If you wish to put on a winter-grade down jacket when you sleep it can make for a decent match. This could be a draw back if you wish to prolong the temperature vary of the luggage through the shoulder seasons. Having stated that, they may match an insulated sleeping bag liner with out situation, in order that is likely to be a greater choice for shoulder season journey. If you get chilly ft, you might put on a pair of down booties contained in the sleeping bag to remain heat.
When I examined the sleeping bag I discovered that the SynergyLink Connectors did a great job of protecting the sleeping bag going through up. When sleeping on my again the Hyperion Bag was nice, good. When I rolled over and slept on my aspect it was surprisingly good. I believed it’d casue a problem nevertheless it didn’t.
When I slept on my again, which I tend to do every now and then, I discovered myself caught contained in the hood. This is my solely criticism of this bag simply concentrate on this. A abdomen sleeper could 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 shall be value it.
Overall, the Therm-a-Rest Hyperion Sleeping Bags are tight-fitting sleeping luggage resulting from their inner dimensions. If you’re obese, look elsewhere, this bag is not going to be just right for you. If you’re of common construct or smaller then this could possibly be the proper ultralight sleeping bag.

Warmth
When testing the bag I discovered the temperature score to be true to these acknowledged by Therm-a-Rest. Both the Hyperion 20F/-6C and Hyperion 32F/0C sleeping luggage have been examined to EN and ISO requirements so you’ll be able to relaxation assured that the sleeping bag will preserve you heat on the temperatures as reported.
I’m usually a barely chilly sleeper until I ate a really heavy meal earlier than going to mattress (which may preserve you hotter at evening). I’m a aspect sleeper normally and I discovered the bag to work properly when sleeping on my aspect however not so good when sleeping on my again.
It is tremendous necessary to notice that there are 3 temperature scores listed on every sleeping bag.

The Comfort Rating is an important score as that is the temperature at which you may be heat and will sleep properly. Unfortunately, the sleeping bag trade as a complete fails to make use of this score for advertising and marketing causes. But use this as your base for what bag will preserve you heat at what temperature.
This is often the temperature at which a lady will sleep properly with out being chilly.
Limit Rating
The Limit Rating is utilized by virtually all sleeping bag producers because the temperature score for the sleeping bag. Few individuals will get a great evening’s sleep on the restrict score until they know their our bodies properly sufficient to know they’re heat sleepers.
I do know myself properly sufficient to know I’m often midway between the Comfort and Limit Rating of an authorized EN/ISO examined sleeping bag. This is my very own private score of how heat I shall be at evening inside a bag.
This is often the temperature score {that a} male, curled up on his aspect, will sleep OK. Most individuals will really feel chilly and never sleep properly when sleeping on the restrict score temperatures.
Extreme Limit
