Sea To Summit Reactor Extreme Thermolite Mummy Liner

Don't Leave Without It

I was very reluctant to buy this at first, I like to keep my pack to a minimum, but a friend convenience me before going on a winter backpacking weekend, and I couldn't be more thankful. It's so cozy, stretchy, soft, and totally transformed cold weather camping for me. In fact, I love it so much that I take it with me even in the warmer months as I found it to be useful for a number of things, like a light layer for star gazing, a back-up pillow (before I got a Sea to Summit Pillow), and an e...xtra cover for a furry friend when it was just warm enough for me to go without but my pup looked like he might want some comfort. After a year of having it, 9/10 times I don't leave without it.

Game Changer

I bought this to supplement my 25 degree sleeping bag while camping in Northern California in 30 degree weather. I had previously camped in Utah in similar temperatures without it and been consistently cold in my sleeping bag. Once I had the liner, it made a clear difference. Other people I was camping with reported being cold at night and I never felt it. I also layered my Sea to Summit Coolmax with it for an added layer. Would definitely recommend for people who run cold.
