      I usually freeze if it's not Texas summer hot on a campout. My husband purchased this for me, and it's been great! My two sons like it, too, so much so, that I just purchased two more!

      Comments about Sea to Summit Reactor Extreme Thermolite Liner:

      This liner is great! It fits in any mummy bag I have, it is light weight, and it is warm. I bought this for my boyfriend to use with a North Face 20 degree synthetic bag while Winter camping and he stayed very warm. He is 6'2", and he fit inside very well. It did not get below zero at night but it was definitely colder than 20. I plan to use this liner as a summer bag too for more light weight trips in the heat.

        Comments about Sea to Summit Reactor Extreme Thermolite Liner:

        Scouting in December, 24 deg nite w/ 15 deg bag, this liner captured heat and maintained dryness. Had my doubts but but slept comfortably. B/A Lost Ranger, w/ Sleeping giant and this liner inside made me a well rested scout leader. Small in pack, big in heat retention=I see value in this $50-60 liner, hope it lasts long, we will see.

        Comments about Sea to Summit Reactor Extreme Thermolite Liner:

        So my wife and I went on a big National Parks road trip for a month. We hit Tetons, Yellowstone, Glacier, Jasper, Banff, and the Badlands. Not expecting freezing temps, we only had 40 degree bags and the extreme thermolite liners. In Yellowstone, the temp dropped below freezing. We had all of our clothes on with beanies and wool socks, and we could barely sleep because we were so cold. If we didn't have the liners, we probably would have slept in the car with the heat on. So, they help if you want a little something extra in case it might be colder than you think. But, do not rely on a 25 degree boost.
