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!!

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

This Liner Blew My Mind!

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!

I Have Not Used The

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!

Works Perfectly. Just What I

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.

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

I Used The Liner On

I used the liner on a raft trip in UT. It was perfect for the weather. It fit well in my sleeping bag when needed. The fabric is soft. It washed well. I would recommend this product.

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.

It Packs Small, Does Its

It packs small, does its job, and it’s lightweight.

Just What I Needed!

To better maintain social distancing during the Covid Pandemic, I'll be winter camping this ski season, so I don't need to stay at a hotel or lodge. This liner is going to help me tremendously to keep me warm!
