    Comments about Sea to Summit Coolmax Adaptor Liner:

    I haven't used a sleeping bag liner until now because I thought I would feel constricted. The fabric on this liner is a bit stretchy and is so comfortable. I also love that I don't wake up covered in sweat anymore. Plus it protects my sleeping bag so that I don't have to wash it as often.
