      Haven't had it on the trail yet but love the liner. I hate the feel of sleeping bags when I'm trying to sleep. This will do the trick. Cost effective, lightweight, smaller than a pop can.

        Comments about SeaToSummit Sea To Summit Adaptor CoolMax Travel Liner:

        I bought this to get some additional warmth and also to keep my sleeping bag clean. Its a lot easier to wach the liner than the sleeping bag.

        I actually used this in very cold conditions (0F) for the most part. I felt it added 5 or more degrees of heat to the sleeping bag.

        Worked out very well for me.

          Perfect for hot summer backpacking. Lightweight and comfortable. Cuts down the breeze, keeps me cool and helps prevent sweat from evaporating directly off the skin, chilling me while I sleep.

          Comments about SeaToSummit Sea To Summit Adaptor CoolMax Travel Liner:

          No surprises. I knew what it costed and I knew it would be light, compact, and comfortable. Seems to me that anyone with a modicum of sewing expertise could put one together for around $5, though. Sea to Summit certainly knows how to capitalize on the minimalist camping craze.

              Found the liner to serve adequately. I still got a little sweaty at times- but would agree that the liner probably does add about 10-15 degrees warmth to my bag.

                  Comments about SeaToSummit Sea To Summit Adaptor CoolMax Travel Liner:

                  The cool max, used as a stand-alone sheet is very comfortable on the body. It is very thin but seems quite durable and stretchy. I used this on my Havasupai trip. I did not, nor was it intended to keep me warm. It was to keep me comfortable and it did that quite well.
                  In the early evening, I did not feel hot or end up sticking to my Thermarest and as it cooled off, I was still quite comfortable. In the early morning when the temps dropped, I woke up with my knees cold. I tossed a shirt over my knees and went right back to sleep.

                  I expect that this adaptor will make my mummy bag more comfortable. I never encountered any hot spots where you feel moist or sticky causing you to stick to your bag, tent floor or pad. I assume it will function the same when I use it as a liner.

                  All in all, I'm happy with the item at least for my first use at 3 nights in the canyon.

                      This is only a light weight bag used for summer use only. Below 60 degrees , this would not be adequate depending on the person using it.

                    I asked if this was a rectangular liner. Your response was:
                    "The Sea to Summit Adaptor CoolMax Travel Liner is rectangular....dimensions are 82 in. x 35 in. All of the Sea to Summit coolmax liners are rectangular. This is a mummy liner"...

                    So which is it? Is it Rectangular or Mummy shaped?
