Summer Liner/Insect Shield

Used this as a summer bag and as a bug shield while backpacking. Super comfortable and will use as a liner when the weather turns colder with my quilt/ mattress. Very happy with the product!!

Light and comfortable

I bought this for use in mountain huts and it's just right. It's lightweight, thin and soft. My only complaint is that the stuff sack is a bit too big and it could compress smaller to save more space.

Very comfortable on those hot desert nights. This replaced my 10+ year old sea to summit liner.

I have not used the product as of now. I had plan to do more camping but had other priorities. I know this product will work for me. You folks design very good products. I already own and use 6 of your products for camping.

I can finally sleep through the night!

Idk how this material is made, but it?s changed my life! As a hot sleeper and as someone who?s done sleep studies for not sleeping, I feel like a real human now. I was too excited to wait for my next backpacking trip to test it out, so I gave it a shot one night and slept through the WHOLE night. And been doing it ever since. Maybe I needed to be swaddled like a child? home or in the forest, I can finally sleep. Now I?m wondering how do I get this material in a full bed set?!

Love this bag liner!

I sleep hot and was looking for something that could double as an extra layer under a quilt on colder nights and be used by itself on warm and humid nights. This product is perfect! It?s very lightweight for backpacking yet substantial enough to get the job done. It?s breathable so no sweating yet provides the covering to prevent drafts/chills. It?s soft to the touch and stretchy and roomy - perfect for someone like me who sleeps in all positions and tosses and turns at night. The pillow pocket is a great perk for keeping your pillow in place?and creates an area to tuck your hands and arms inside, keeping them lightly covered when stomach sleeping. Love this purchase and so glad I made the decision to get it!

Perfect!

I bought a Coolmax for myself 2 years ago and loved it so much I just bought 2 more for my sons and my husband bought one as well. It really keeps the oils and dirt from a day or three worth of hiking off of my very expensive quilt. It's machine washable, which is much easier to wash than a quilt when IT gets dirty and oily! I also love how I can use it as my sheet it the summer days.

Great liner

Just got back from a 6 day backpacking trip through the High Sierra's in Yosemite. I used this liner with a 20 degree bag mostly to shield it from the grossness I would inflict on my bag and it worked wonderfully for that. As a bonus, the first night in the valley was a low of 58 and I slept only in this liner on top of my bag and it was great! The only small issue I have with the liner is that it is a little difficult to get in/out of for a midnight nature break

Compact and washable

Love the coolmax liners They were perfect for traveling cross country as well with my sleeping bag I don't like to sleep directly on hotel bedding These were perfect, lightweight, and compact Took me just a second to adapt to no zipper as my other one had one I actually prefer my no zipper liners now.

Wicks away sweat

I love this liner! I had originally purchased this for camping. But it also works great for hot flashes/ night sweats. It makes sleeping SOOO much more comfortable. It?s nice and stretchy and roomy. Honestly I have actually walked in it. It also falls to the ground easily if you need to get out of it. It?s sheer and flowy and wicking. It is very well made and stands up to frequent washing. The only complaint is that once it is out if the bag, it doesn?t fit back in easily. The back could be larger so it stows easily.

CoooolMax liner

Great liner insert, didn't get to use with DEET yet so didn't give it 5 stars as I am unsure how well it will hold up. Besides my worry with DEET, the liner was perfect. Nice enough to use a lightweight blanket on warm nights.

Super Cool COOLMAX!

Love its lightweight, compact design. Perfect for a good night?s sleep in a hot Arizona canyon. I?m excited for the opportunity to pair it up with a sleeping bag for when the temperatures drop.

Used one for work, had to get my own. best material with stretch to add wicking and cooling to sleeping bag

Great when used on it's own or with a sleeping bag. Good wicking properties and adds a dimension to your tent. One of the best I've used, and I've tried many brands and materials. For the weight, it's well worth it
