Sea To Summit Reactor Thermolite Sleeping Bag Liner

The Sea To Summit Reactor Thermolite Sleeping Bag Liner weighs only 9.2 ounces, adds up to 15 degrees to your sleeping bag's warmth, and packs to a tiny 3 x 5 inches. The key to this Sea To Summit sleeping bag liner's excellent stats is warm, breathable hollow-fiber Thermolite material. This sleeping bag liner weighs less and packs smaller than a comparable fleece liner, which makes it ideal for both backpacking and nights in the hostel.

Bottom Line: Sleep warmer and more comfortably thanks to the soft Sea To Summit Reactor Thermolite Sleeping Bag Liner.

I expected a bit more.

I don't see how this really adds 15 degrees of warmth, though I still use it as part of my down system. Like any other liner, it helps keep the sleeping bag clean, packs small, and weighs little. Soft material feels great. It is honestly so thin that you can see through it, though I took it to the smokey's in TN this summer and used it alone as my sleeping bag.

Waiting for a better solution

This fabric liner is effective -- though doesn't really add 15 degrees of comfort to a 3 season bag. The stuff sack doesn't compress, and is just big enough for the sack. In my experience, it is way too much work to get it back inside; I just add it to the compression sack that I use for the sleeping bag. It does look like it would work nicely as a stand-alone bag in the hot weather.

Worth the money

I bought this liner after reading some reviews about it and became instantly skeptical when I saw how thin the liner is (as someone said, you can see through it) but I was impressed by the liner. It doesn't give the 15 degrees it says (10 is more accurate) but it can't be beat for comfort or packability

I've used this liner for awhile now, and it is definitely nice to have on the cold nights. I agree that it doesn't quite add 15, more like 10 degrees to your bag. It also feels nice next to your skin and adds quite a bit of comfort to your bag.

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.
