        Comments about Cocoon CoolMax Mummy Liner:

        Took this bag liner on the AT with me without trying it out first. Big mistake! It was the first thing I shed from my pack. It was like wearing a giant stretchy nylon stocking, severely restricting movement and comfort.

        Bottom Line No, I would not recommend this to a friend

          Comments about Cocoon CoolMax Mummy Liner:

          As a soldier, space is very limited when i deploy. This bag is great by itself in slightly cool places and wonderful as a bag liner. It may look thin, but it works great.

          Bottom Line Yes, I would recommend this to a friend

          Comments about Cocoon CoolMax Mummy Liner:

          I regularly use sleeping bag liners, primarily to help keep my bags clean. This liner is very comfortable, stretching and comforming easily if tossing and turning is the order of the night. Have also used it by itself on warm summer nights. I would like to see an option for some kind of side opening. Climbing in or out from the top can be a little awkward.

          Bottom Line Yes, I would recommend this to a friend

          Comments about Cocoon CoolMax Mummy Liner:

          Will not go into the cold woods without this item! It makes my +20 degree bag really +20 degrees! If you like to sleep in your briefs and not all your clothing this item will help you do that.

          I started off a night in my briefs with temps in upper 30s. Around 3am the temp dropped to 26 degrees. I woke up some what chilled in my NF +20 synthetic bag. I slipped into the liner and stayed in just my briefs to see how it worked. WOW! I was toasty warm the rest of the night.

          It's also nice to not have to slip into that cold nylon either.

          Can't wait to use it for hot days instead of a big sleeping bag here in Texas.

          If you sleep kind of cold, GET THIS ITEM! You will love it!

            Wicks away moisture unbelievably well! Perfect for warm, humid nights to use alone as a bag. Ultralight and small. Very practical and worth the money!!

            It was a little colder than we anticipated in the higher altitudes---the sack was warm enough, but we would have liked something a little more substantial-----we were not cold, so it was fine.

              I found this liner to be a great summer bag for early night time, offering a little coverage without making me sweat. It also turned out to double as a superb mosquito netting, though I suppose you could find a lighter net. I was happy with it in my average-weight pack, but I may rethink when I go UL.
