Summer Liner/Insect Shield

[This review was collected as part of a promotion.] 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!!

This liner blew my mind!

[This review was collected as part of a promotion.] Fantastic in the humid southern Florida climate that is the Everglades! Took out several tours for multi day excursions in the 10,000 Islands area of ENP and this was a life saver. I sweat a good deal, and sleeping bags of any sort have never been a good fit for camping in this environment. The adaptor COOLMAX Liner is a fantastic option for comfort in hot and humid conditions. Great wicking and velvet feel. This is like a swamp cocoon that will make sleep in the least comfortable of conditions both do able and extremely enjoyable!

[This review was collected as part of a promotion.] 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!

[This review was collected as part of a promotion.] 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!

[This review was collected as part of a promotion.] Works perfectly. Just what I needed for light weight liner for my lightweight summer sleeping bag. I will be using it in June for a 114 mile backpacking adventure

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.

Love this product

Perfect for a great nights sleep and packs light. Still feels great after multiple washes.
