Product Reviews
Rated 5 out of 5 by from Really capable I have only tried a handful of sleeping bags as i'm pretty much a rookie hiker. However i am absolutely amazed by how this bag performs. I can compress it to the size of a football! thisi is reallt usefull to me when i go bike packing, when pack size is important. I always use a small liner, but i have never had any chills in this bag. even at around 0 degrees celcius. some people mention it is is chilly, but it seems most of those people are using the uber lite, or some similar sleeping mat. end of the day im super impressed with its weight to warmth ratio and it has yet to let me down!

Rated 3 out of 5 by from Extremely light Used this and their neoair uberlite on a recent camping trip north of Milwaukee WI along Lake Michigan; these did not provide the advertised comfort. All their gear packs down extremely light and was comfortable but did not provide warmth or comfort on a 35 degree night. Packed up and drove home at 3am. If this was labeled as 45 degree bag I'd agree with it more but given it's cost I wouldn't recommend it.

Rated 5 out of 5 by from Great lightweight bag This bag is super lightweight, very cozy, and has an attractive color. I'm glad I chose this bag for my 3 season, lightweight backpacking adventures.

Rated 4 out of 5 by from Great weight saving bag I go to the Golden Trout Wilderness about 4 trips per year. This bag is perfect for summer trips, but I need to use a liner for early spring and fall.

Rated 4 out of 5 by from Great Bags I bought this a month ago and love it very much. It's really light and comfy and really small in bag. I use it twice when i go hiking in Taiwan's mountain height is 3000 meter and it work well. It can keeping me warm and comfortable at a 40F night, and i think this is the extreme temperature. Maybe Therm-a-Rest is famous with its sleeping pads, but i think the sleeping bags is also good.

Rated 3 out of 5 by from I wouldn't purchase this again The Hyperion 32 is an excellent bag. The construction is superior but there is a design flaw. It's weight can't be beat. I gave the bag three stars because of the zipper and draft tube placement. It is clear that the bag is made for those who sleep on their backs. As for reality that doesn't happen. I tend to move and the only way I could be fully comfortable, and not get a cold spot along the zipper, was to stuff my down jacket along the zipper. I didn't have any issues with the right side of the bag so it wasn't the strategically placed down. The draft tube is on the top. Cold goes down. So it's placement, on the top of the zipper, I feel, is a design flaw. But I'm still thinking that wouldn't make a difference and a different zipper would. I know for sure it was the zipper because it felt cold and the bag did not. The coldest it got was 35° and that was only one night as the other nights, 5, were 40-45° I do not consider this a 32° bag when I get a draft at 42° and I run hot so I love cold weather. I would rather use my Cat's Meow from 1996. That is a 30° bag with primaloft and is good at 30°. It's the only bag I've had that's rated for 30° that isn't freezing at it's temp rating. Yes, I know bags are rated differently now. The only reason I wanted this bag is because I can drop a pound.

Rated 3 out of 5 by from COLD at 45F I love the size and weight of this sleeping bag. However, it fails at its primary job, keeping me warm at night. Even a 45F night in August and my shoulder gets cold if I sleep on my side. The bag simply does not have enough insulation. As small, lean person I do tend to sleep cold, but my 20F bag from another company easily keeps me toasty down to 20F. The Hyperion 32F isn't even warm to its stated comfort range of 41F. Minor drawbacks that I would put up with for the weight and size are the 2/3rds length zipper and the face cinch system.
