Mountainsmith 0°F Crestone Sleeping Bag - Synthetic, Mummy

I knew this bag was going to be a bit heavy, and it is a bit too bulky for backpacking, but my husband says he will make it work and we couldn't pass up the deal...for a 0 degree bag, this is a stellar deal. Zipper doesn't snag, but if you are taller than, say 5'11" this bag won't be long enough for you. My husband is barely 5'10" and he fits perfectly in it, with no room to spare in the hood. Very comfy, have yet to test its durability.

Stayed warm in 0 degree weather. This is listed as accommodating someone up to 6' 4"... I'm 6' and that's about all this bag will work for. I understand being tucked in tight for cold weather but I do not think a taller person would fit well... Neither would a thick person. This bag is very warm, but it is tight. Packs down well and is pretty light for a cold weather bag.

This is a sleeping bag for my son, who is in scouts. He camps out once a month including snow caving. He camps in the Sierra's every month. I would not recommend the bag for an sadult, too short and small.

I tested this bag in my living room at 67º. Bag was too small and tight in shoulders. I'm 6', 185lbs. Also, I felt comfortable in bag in my living room. I should have been warm zipped up in bag. I do not think this bag would keep me warm in temperatures below 40º. It is advertised as a 0º bag. Bag would be OK for spring/fall and summer. I don't think it would work for cool-cold nights.

This is an amazing bag, although (as with most bags) would be chilly in 0 degrees. I used it for four days in the Gila Wilderness, including a night at 9200ft where it got down to 10F and it was barely warming. Quality, light, and packs small though!

Very good price! comfortable, warm. I have had trouble getting the hood as tight as I prefer. It fits me well, 5'9 140lbs.

This is a pretty solid bag. Loft isn't as large as a down zero degree, but still packs fairly small and is definitely warm. My buddy just got a twenty degree synthetic, and it packs smaller than the crestone; that's why I said it packs large. I'm 5'11" and it fits quite snugly. After about 10 minutes of being in the bag in 35 degree weather with wind, in a hammock, I about started sweating. Overall, I think it's a great bag.

I took the sleeping bag up to Eagle Cap and it got rather cold at night, The bag kept me warm and cozy and didn't take up my whole backpack.

Good, entry level sleeping bag. Not a winter bag.

Bought this item to go backpacking. It's light weight and will work just fine
