It’s Helium.Verified Buyer Reviewed by Dan from NYC on Saturday, April 14, 2018Perfect sleeping bag.
Doesn’t need to explain.
Draft Collar DodgerReviewed by Rico Hardcore New Mexico from God's Country U.S.A. on Thursday, December 21, 2017I really liked this bag! The warmth to weight ratio is incredible. The one thing that is missing, however, is a good Draft Collar. The Krypton has an overstuffed collar but no pull string to cinch it up around your shoulders on those bone chillin', teeth chatterin' nights when you left your longjohns & 0 degree bag back at the casa. I want my cold weather sleeping bag to have a draft collar on it. Since this bag didn't, I sent it back. With STP's excellent return policy & service it was "No Worries!"
Roomy, light bagVerified Buyer Reviewed by Wayne the farmer from Montana on Wednesday, August 31, 2016I weigh 185 lbs. and am 6 foot tall. Because I roll around a lot at night I ordered the long bag. It is really roomy, especially around the shoulders. It is also amazing light weight. The only shortcoming I noticed (I haven't slept in it yet) is that it doesn't have a draft tube around the zipper. I would think that a bag that costs $300 should have one.
Soft 4 - just because I haven't used it much yet.Verified Buyer Reviewed by Matt in Michigan from Michigan on Tuesday, August 30, 2016I have to give this bag a "soft" 4 stars for the time being. I have not yet used it in the wild, but I have napped in it once to test out the fit and general comfort.
Now, this is a "Long" so I think is supposed to fit up to 6' 6", IIRC. I am a hair over 6', muscular 200#, wide shoulders. I am a side/back sleeper, and I often like to have my arm tucked up under my head/pillow. As far as the fit of this bag is concerned, it was great. I have slept in regular sized mummies, as well as longs. This definitely is a long. My feel normally compress the insulation at the end of the footbox, this means it diminishes the insulation properties. This footbox had lots of loft.
My only complaint at his point, is the smell of the bag when I got it. It had a bit of the chemical smell. I think it is from the bag itself, but I separated the bag and its two sacks to see. It comes with a mesh storage bag to retain its loft, and a stuff sack for packing. I won't likely use the stuff sack. I probably use a different compression bag.
Since its still a humid 90 degrees here in Michigan, I won't be able to give this a real test until at least October.
lightweight warmth.Verified Buyer Reviewed by Steve from Pennsylvania on Wednesday, August 17, 2016I was looking for a winter backpacking bag and found it in the Krypton. very lightweight and warm. Haven't used it in wet conditions yet.

“Hey I am was just checking the specs on this bag. I am about 5'2" and a slight build do you think this bag will be overly roomy for me. I have struggled with finding a good warm bag that is not seriously heavy for packing long distances but will still keep me warm and dry. My last one was to big for me and did not keep me warm. If you don't recommend this one to me do you have any other suggestions. I do need one rated for colder temps because when hunting in September in Alaska it does drop to below freezing frequently. ”
It will be longer than you need, but it does give you the ability to put tomorrows clothes in the bottom to warm them up before you put them on. You should check the girth against your frame as well, to know if it will be too big around.
Girth (shoulder/hip/foot): 64/58/40"
Fits to: 6'6"
“Is this sleeping bag really 91" long? I know the "long" bag fits people up to 6'6" (78") but what is the additional 13" length for? I could understand an extra 6-8" for comfort however over a foot extra seems excessive. Just wanted to double check the dimension is correct. Thanks!”
