      Comments about SeaToSummit Sea To Summit Thermolite Reactor Extreme Mummy Liner:

      I have not used this liner yet, so I can't say if it adds as much to the sleeping bad as claimed. I am little disappointed it does not have a side zipper....it would sure be easier to get in and out of with a zipper.

          It packs tiny and is light and warm. What else can you say about a sleeping bag liner? I asked it to read me to sleep but it refused.

            Tried it out on a winter camoing trip with my brother. It added no noticable warmth. Seemed like a good liner for liner sake. Bottom line is, that if you are buying it to make your bag warmer -don't-. If you need a liner, it's alright.

              this item works well enough, but the price is far too high for what you get. if i didnt get this on sale, i would have been pretty upset. there are other similar items that work just as well, and are just abt as light & compact at a much lower price. maybe that's why it was on sale, huh?

                The liner is being used to improve the thermal value of my 4 season bag during colder than expected conditions. It fits the bag well, is comfortable, and pack in a compact bag that is light.

                    There is no sipper on this liner. You just shimmy into it.

                    The Sea To Summit Thermolite Reactor Extreme Mummy Liner is a fleece material. A standard VBL is a coated nylon sack.

                    Not meant to be used by itself. If used by itself, then only for summer nights.
