This liner is awesome. I have the thermolite reactor, that I also bought from LLBean, which only gives up to 14 degrees in warmth, and I love it. I needed another one for my daughter since we were going on winter camping trips and her fleece liner wasn't cutting it.
This liner proved to be the way to go, especially since I really like the other one I have. My daughter loved how small it packed up and it didn't take a lot of room in her pack or add on a lot of weight. She was really warm all night. I would highly recommend this to anyone who is doing camping in the cold and wants an extra layer of warmth without sacrificing additional space or weight on your pack.

I found this to be large and comfortable. The reason I chose this particular model from Sea and Summit was because I am specifically using it to increase the warmth of one particular light weight sleeping bag. It will also be a liner to keep my other sleeping bags clean. You do need to crawl in from the top but I am used to that. Since there is no opening on the side it keeps you warmer.

This bag does do a good job of keeping you warm. But when you get into your sleeping bag you sit down on it, get your legs in and then zip it up to the comfort level you desire. However, using this liner you cannot operate that way because it doesn't have a zipper. You must put yourself into it from top to bottom as it is actually a giant sock! Once you do that your hands/arms are restricted when getting into your regular bag. Also, if you need to move around or get out for a potty break the frustration just gets worse as you have to wrangle your arms up out of the top of this liner, then operate your bag zipper. After that you have to stand up so the liner falls to your feet before you are free of it. I'll be finding a seamstress that can add a zipper at least 3/4 the way down the top. Otherwise, this liner feels like being in a trap. Find one with a zipper and don't get this one.

As an airline crew member, I use this sleeping bag liner rather than a bulky blanket in the crew bunks when working or in the cabin when I am a passenger. Standard blankets can slide off. With the bag liner, I can roll over and never lose my cover. When I am finished, I just stand up and drop it to the floor, then pack it in the small bag. It washes well too.

In the store I placed my hand inside the bag and could feel the heat from my hand being radiated back to me; it felt very warm. In the field the bag works well, feels very cozy, and added about 10-15 degrees to my down bag. It was especially helpful in keeping my feet warm. And it's perfect as a warm weather sleeping bag on its own in weather over 60-65 degrees.

the thermolite reactor extreme slepping bag liner is great and effective. It is soft and fleece like and works well inside a sleeping bag. Feels like a real blanket and adds warmth to your bag. However depending on you and the type of sleeper you are you may not get the results the tag says. it says it adds up to 25 degrees but for me I hink it adds a comfortable 10-15 degrees. Not bad. The real dig to this product is its warm weather advantage. No longer do you need bulky blankets are sleeping bags for warmer nights. this little water bottle size stuff sack will do just fine. You only have to carry about 7 oz.
