Sea To Summit Reactor Thermolite Sleeping Bag Liner



works, but I'm not convinced it's the best
Essentially this is a giant polyester sock. It feels quite thin (you can see through it if you hold it up to light). I don't know about 15 degrees, but it did add a noticeable amount of warmth to my 30 degree bag on a cold night. The drawstring comes out on the left by default but with a little effort I moved it to the right. I didn't feel like it inhibited motion in my sleeping bag, and it was relatively easy to get in and out of. It may be a little heavy (and expensive) for what it does. After all, it won't be as efficient as down for its weight. If you bring it and don't need it, at least it makes a decent pillow.
