Therm-a-Relaxation Hyperion Ultralight Sleeping Baggage

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. And the Hyperion vary is unashamedly focused on the backpacker who needs the lightest attainable sleeping bag with the best attainable high quality.

Therm-a-Relaxation has seen no must make any adjustments since that point as it’s nonetheless among the finest ultralight sleeping luggage available on the market.

The temperatures of the baggage 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 rankings on the Hyperion sleeping luggage have been examined to this commonplace. Personally, I like this dedication to making sure the sleeping bag rankings are independently examined quite than a greatest guess on how heat you ought to be like some firms do. Extra on the temperature rankings somewhat later.


Down sort/fill energy

The Therm-a-Relaxation Hyperion Sleeping Baggage are stuffed with 900+ loft Hyperdry Goose Down in 2022. That is the top-of-the-range down used on any Therm-a-Relaxation Sleeping Bag. It’s not solely ultra-lightweight but in addition has good water resistance qualities as they use Nikwax water repellent down. This implies in case you are unlucky sufficient to seek out your self in very dangerous climate and your sleeping bag will get moist, it is not going to soak up as a lot water as different sleeping luggage and nonetheless be capable to loft and hold you heat.


Building

Let’s check out how the Therm-a-Relaxation Hyperion Sleeping Baggage are made with the options such because the Inside 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 forestall drops of water from coming into the bag. Like nearly all trendy ultralight sleeping luggage, the material mild and nearly see-through, particularly once 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.


Inside 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’s not solely ultralight but in addition resistant to ripping.

I did the rip check 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 might 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 affirm it would present an honest stage of water resistance that’s at the very 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 exterior below the celebrities when condensation comes down in a single day.

Disclaimer: I don’t advocate that you simply 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 somewhat completely different from different sleeping luggage available on the market. Whereas the field baffles are not 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 which means is the layer that’s dealing with down onto the sleeping pad has much less insulation and the highest layer does all of the work of preserving you heat.

In concept, this method is nice. However there’s one problem. What occurs once you roll over at night time the 70% of the insulation is on the underside? Effectively, if this happens you’ll not keep as heat. To fight this, the Hyperion Sleeping Baggage 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 method I discovered it to work surprisingly nicely. Anybody who has used an ultralight backpacking quilt might be aware of such a system, however sleeping bag homeowners are usually not so aware of such a system. The sleeping bag stayed in place nicely 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 snug and never have the hood cowl my mouth.

Like most ultralight sleeping luggage, I’d have preferred every baffle to be filled with 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 reality, it would must be carried out on occasion to maintain the bag acting at its greatest.

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 interior draft collar. I used to be in a position to snag the zip after I tried however for most individuals, there’s nothing to fret about. There’s a little bit of a studying curve in terms of utilizing the zip and locking it in place with the press stud subsequent to the hood. Once 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 difficulty, and after just one night time of use, it’s simple sufficient to make use of.

Total, the zips and draft tubes do a very good job and there’s not a lot that may be faulted. However 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 is sweet and contains a full collar the entire method round. It’s a very tight match and in contrast to many different sleeping luggage, it is not going to be attainable to sleep along with your backpacking pillow contained in the hood. The hood is simply too tight a match for that. Should you use a backpacking pillow it should be exterior the hood. This isn’t a giant problem however one thing you could concentrate on. That very same compact dimension of the hood ensures there are usually not many air pockets that take power to warmth, power that’s higher spent preserving you heat.

The Drawcords and toggles used to cinch the hood closed all work as anticipated and won’t be a difficulty for customers.

The neck and hood collars might be somewhat 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 ends up in the down changing into extra compressed and clumped, making them much less environment friendly at preserving you heat.

Once I examined the Therm-a-Relaxation Hyperion Sleeping Bag I spent a whole lot of 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 might discover no higher ultralight sleeping system than this.

As talked about above, perhaps a bit extra overfill within the hood and draft collars could be a very good enchancment. And I barely bigger match could 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 well 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. In reality, the Hyperion is essentially the most compressible sleeping bag in its class of ultralight sleeping luggage. Others could come shut however that is the perfect, 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 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 dimension.

Consolation

The interior sizing of the Therm-a-Relaxation Hyperion Sleeping Baggage is on tight dimension. There may be not a whole lot 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.

Though the Hyperion fashions are traditional mummy-style sleeping luggage, they’ve very compact inside dimensions. In reality, their inside dimension are one of many smallest of their class. These compact inside dimensions permit for a higher potential to maintain you heat as you waste much less power preserving air pockets heat. Because of this, 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 once you need an ultralight sleeping bag.

The tight inside dimensions have some adverse elements that must be highlighted. If you wish to put on a winter-grade down jacket whilst you sleep it would make for a good match. This generally is a draw back if you wish to prolong the temperature vary of the baggage in the course of the shoulder seasons. Having stated that, they’ll match an insulated sleeping bag liner with out problem, in order that may be a greater possibility for shoulder season journey. Should you get chilly toes, you possibly can put on a pair of down booties contained in the sleeping bag to remain heat.

Once I examined the sleeping bag I discovered that the SynergyLink Connectors did a very good job of preserving the sleeping bag dealing with up. When sleeping on my again the Hyperion Bag was nice, excellent. Once I rolled over and slept on my aspect it was surprisingly good. I assumed it would casue a difficulty but it surely didn’t.

Once I slept on my again, which I generally tend to do on occasion, 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 difficulty with this bag. Having stated that, most individuals hardly ever sleep of their abdomen, so for most individuals, the compact dimension and ultralight weight might be value it.

Total, the Therm-a-Relaxation Hyperion Sleeping Baggage are tight-fitting sleeping luggage resulting from their inside dimensions. If you’re chubby, look elsewhere, this bag is not going to give you the results you want. If you’re of common construct or smaller then this might be the proper ultralight sleeping bag.
