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.
