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

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

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

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.

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!

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.

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.

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.

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.

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.

Love this sleeping bag. It packs very small, is very light, very comfy, and just roomy enough. The shape is very good. I have fairly wide shoulders and was afraid I would feel cramped, but there is just enough room for me to switch sides in the night and not get all bound up. On a cold, sub 40° night at high altitude, I did get pretty cold. I typically sleep pretty warm, but I've also gotten used to my x-therm mattress. The Hyperion paired with the UberLite mattress is a small, lightweight sleeping system that shouldn't be used at temps below 40°. But anything above that is spectacular. My only complaint about this bag is the SynergyLink Connectors. They are a joke. The little connector system needs to be actual clips, not a T into loop style. My first trip, I lost one of the straps high in the mountains. I am very good at keeping track of all the bits and pieces of my gear, yet somehow a strap went missing. So much for Leave No Trace. When I get another strap to replace the missing one, I will be modifying them both to have small clips instead of the slip through design.

I used this sleeping bag on a week-long (46.6mi) coastal camping trip in British Columbia and I couldn't have been happier with its performance! My old sleeping bag was purchased back in 2010, so the difference was like night and day in regards to the size that it packed down to as well as its overall weight. The packed down size was much smaller than what I was used to and I was extremely impressed with how compact this bag truly is! Its overall weight was considerably less than what I was accustomed to (weighing in at only 1-pound!) as well and it was extremely cozy and warm when it came time to crash for the day, even on the coldest/wettest of nights along the coast. The SynergyLink? Connectors were just icing on the cake, I've never had a bag with anything like these before and each morning that I woke up I was still firmly attached to my sleeping pad.

I used to think that going ultralight was cutting some comfort, warmth, or was too costly. This bag is fairly priced especially considering all of the benefits I got during a week long through hike in Canada. It helped cut my sleeping bag weight down by over 2 lbs packs INSANELY SMALL and I also found myself toasty warm (typically always cold) with space to sleep on my side. This helped keep my pack light on my back while simultaneously able to get a good night sleep so I wasn't a grouch to my partners the next day and could enjoy the amazing scenery well-rested and wide-eyed.

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.
