    When it’s too hot and buggy to sleep, break out the Adaptor Liner.

    In the hot, humid, and buggy corners of the globe, get a cool night's rest when you wrap up outside in the Sea To Summit Coolmax Adaptor Sleeping Bag Liner. When you sleep in this liner by itself, the Coolmax material transfers moisture out away from your body and stretches as you dream about the next day’s travels. The Adaptor also works with your sleeping bag to keep it dry and clean when the temperatures dive. And when the insects are diving and buzzing, the odorless Insect Shield treatment repels mosquitoes, ticks, flies, and fleas for scratch-free nights. The invisible repellent remains effective through six months of exposure to weathering or through 25 washings. The lightweight liner comes with an included stuff sack so you can throw it in your backpack without sacrificing food space.

    Clean, like whistle.

    • Familiarity: I gave it as a gift but have feedback to share

    My mom picked up one of these because she was worried about sweating in her brand new sleeping bag. After a couple of 35-45 degree nights, she reported feeling warm, comfortable, and clean - she is quite pleased with the liner.
    I've grown used to the feeling of sleeping bag material next to my skin but I can't say that I'm overly fond of it. I felt her liner, I'm really impressed with the texture. This liner is thin and very, very soft. I can see this really improving comfort, both on warm and chilly nights.


      This really helps beat the heat. Often times in the summer where I go camping it gets down to maybe 60-70 degrees with very high humidity. I would just sleep in this. I also like using it inside my sleeping bags, because it helps keep skin oils and sweat from getting onto the sleeping bag fabric, requiring me to wash it to keep it clean. Excellent product.

      Good for heat

      • Familiarity: I've put it through the wringer

      I really like this liner. Used it a lot when I was in Central America. Great for use on its own. Good for keeping your sleeping bag clean. This thing is much easier to clean than a bag. The only thing I don't like about this liner is that it snags on your hands and feet when they are rough from hiking around and such all day. Other than that its great.

      I call it my body sock

        This thing is perfect for warm, humid nights. I bought it for camping in tropical, mosquito-infested areas and it does the job beautifully. I never feel hot or stuffy in it, but its just enough cover that you don't get a chill when a slight breeze rolls by. I use it by itself more often than I use it as a sleeping bag liner, though I have used it as a liner on backpacking trips in colder and drier climates and it still works well to add a bit of warmth and comfort. Oh, and I haven't gotten malaria or japanese encephalitis yet. Woo!

        If you really want a liner for drier and colder climates, use the STS Thermolite Reactor.

        Best Answer

        I own at least one of every type of liner normally available.
        Out of all of them the Coolmax liners are the ones I use almost all of the time. I like it much better than silk.
        I live in Texas and I just sleep in the liner about half of the time I camp out which is almost monthly.
        I have sold many of my fellow Scout leaders and the Scouts themselves on the Coolmax.
        I hope this helps you in your search for a liner.
