Rated 5 out of 5 by from Perfect for warmth in the mounty My son used this on a Boyscout trip to the Rocky Mountains. He said it was perfect for keeping him warmer inside his sleeping bag. It was also amazingly simple to stuff back inrl the sack

Rated 5 out of 5 by from Soft feeling Well I like about this the best is the soft feeling of the material compared to a silk liner this one feels much better next to the skin plus you can machine wash it without any issues

Rated 5 out of 5 by from Snug as a Bug Went camping in a 20 degree bag over the weekend. It ended up getting to 25 degrees with 40 mph winds and sleet. To say this least, this little liner saved me from imminent frostbite. Now that I have lived to tell the tale, I would recommend this to anyone else that is under prepared for the surprise weather.

Rated 4 out of 5 by from Definitely boosts the bag I've gotten to use this a few trips in cold weather. It definitely helps boost the capability of the sleeping bag, however it isn't as well featured as I think it should be for the cost. I could pretty easily make one for less.

Rated 5 out of 5 by from I purchased this item with a 15-degree sleeping bag in preparation for a trip to Mount Rainier. I have only used it once since purchasing on a 40-degree night. I was in short-sleeves so this felt good to pull up over my shoulders without having to go full-mummy in my sleeping bag. In other words, it adds some versatility that I appreciate. Especially worth it considering size and weight.

Rated 4 out of 5 by from perfect fit! We purchased a couple of these to line our hammocks for a backpacking trip in Hawaii and they were just the right layer! Excited to try them out in the sleeping bags in MN.

Rated 4 out of 5 by from Soft and noticeably warmer I really like the "feel" of this liner and its fabric. I wouldn't use it by itself, but combined with one of my cheaper/thinner sleeping bags it made it noticeably warmer which makes it worth the buy. I like being able to increase the useful range of my bag by taking along this compact item. Only "con" is that it is basically a "sock" and I'd rather that it have at least a partial zipper to one side to make it easier to get in/out of.
