Hyperion Sleeping Bag: 32F Down

Best sleeping bag I’ve ever

Best sleeping bag I’ve ever used, and it’s not even close.

Great light weight bag

Light weight and packs small. My favorite bike packing bag! I also prefer the fabric feel to some comparable bags from other brands.

Great product. Super light and

Great product. Super light and warm. Not just for camping but also for staying in hostels during our walk across Spain.

ultralight high quality, a bit tight

Great lightweight sleeping bag! Packs down incredibly small. I would say 32F is a survival limit, not a comfort limit. I’ve had a few uncomfortable nights around freezing temps trying to push this limit with a sleeping bag liner and, well, I didn't die so that was cool. My only complaint about this bag is that the knees are very narrow so there is really only room for your legs to be straight down. My hip muscles were always mad at me after using this bag.

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!

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.

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.

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.

This is the second time. The Hyperion 32 is an excellent bag. It?s weight can?t be beat. The construction is superior but there is a design flaw. I gave the bag two stars because of the zipper and draft tube placement. I?m guessing the zipper is short because of this. I?m also upset that it costs what it does and doesn?t deliver. 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°, 42° Comfort, 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. Shouldn?t have to wear fleece or use an insert at this temp rating. The only reason I wanted this bag is because I can drop a pound.

I wouldn't purchase this again
