Sea to Summit Reactor Extreme Thermolite Liner

rated 5 of 5 stars This liner did exactly what it is supposed to—it made my summer bag 20 degrees warmer. Worth the purchase. Kept me warm and cozy on cold nights. Thermolite used with cheap 45°F bag seen here.  I bought this product to use with my cheap summer sleeping bag so I didn't have to spend a lot of money on a warmer bag. This product worked exactly as it should. It added considerable amount of warmth. There are three different ones and each one adds more warmth. I bought the Thermolite Extreme. It was… Full review

ALPS Mountaineering Microfiber Mummy Liner

rated 4.5 of 5 stars This is a great liner at a much better price point than most. A must to protect and keep your bag clean. Perfect for summer trips, not much help for extra warmth. First things first, I bought this based on a Killer Review on Trailspace. It was super helpful, and there’s no way I could do better, and I agree with all of his points, so definitely check his review out: http://www.trailspace.com/gear/alps-mountaineering/microfiber-mummy-liner/?review=34340   My additional thoughts: Entry & Exit:… Full review

Sea to Summit Reactor Plus Thermolite Liner

rated 3.5 of 5 stars Limited warmth, but soft and comfortable to sleep in. I bought this product last winter to help out the warmth in a cheap sleeping bag, which it did slightly. Sea to Summit claims it will improve warmth up to 25 degrees F. I would guess this liner adds maybe 10 degrees of warmth. I'm a big fan of Sea to Summit products in general, some seem a bit gimmicky or overbuilt but everything I've seen is well made, quality stuff. And this liner is no exception. The liner is basically a soft fleece/flannel… Full review

Jag Bags Silk Sleeping Bag Liner

rated 5 of 5 stars I got this originally for a cross-country travel as I was going to be in a car half the time and in hotels the other half of the time. I got it to have the ability to have a great, warm night's sleep no matter where I ended up on my travels. This has multi-use functions and is great for camping, car camping, hotels, hostels, etc. I would suggest to pick one up as they are not that expensive and great to have around even if the heat in your apartment goes out for a day or two. So many uses and a… Full review

Chinook Pongee Mummy Liner

rated 2 of 5 stars The Chinook Pongee Mummy Liner is a very basic, no thought, sleeping bag liner that might work well for small, short people. Sadly, I can think of no reason at all to recommend this product to anyone. Words of wisdom to start with: First of all... ALWAYS use a sleeping bag liner! A sleeping bag is an investment—usually an expensive investment. The insulation in a sleeping bag, whether down or synthetic, has to be able to create dead-air space to keep the warm air in and cold air out. A bag's insulating… Full review

ALPS Mountaineering Microfiber Mummy Liner

rated 5 of 5 stars I can't believe no one has reviewed these liners! This is one of the best liners on the market! I have two of these, and I've had them for several years. They cost less, are lighter, more comfortable, easier to get in and out of, and out-perform the Sea To Summit Reactor (I have one of those, also). I highly recommend this liner to anyone that doesn't have a liner, and also to those who have the Reactor and are ready for a better liner. --> Before I start the review, let's get the education and… Full review

Cocoon Expedition Liner

rated 4 of 5 stars This liner is super lightweight and the material feels nice and smooth. Keeps skin oils and dirt off sleeping bag, but I didn't find it to add much warmth. This liner is super lightweight and the material feels nice and smooth. I bought it as a light way to keep skin oils and dirt off my sleeping bags. It has a storage bag sewn to the chest area, which is nice so you can't lose it. It stuffs easily inside this pouch when you want. There is no zipper, which I like for the weight savings, but it isn't… Full review

Sea to Summit Toaster Fleece Liner

rated 2.5 of 5 stars Keeps skin oils and dirt off sleeping bag, static electricity attracts hair (human and dog), noisy zipper pull (metal clanking with every movement), bulky. The long zipper makes it easy to get in and out of. The cut seems strange though: zipper starts on your side and crosses the body to end in the middle of the chest. The zipper pull is incredibly noisy — metal clanking with every little movement. I'm considering adding some sort of snap button or something so I can keep it in place during the… Full review

Sea to Summit Reactor Extreme Thermolite Liner

rated 0.5 of 5 stars See through fabric. Can't expect it to hold in warmth. Is expensive and heavy. Will keep a sleeping bag interior clean, but that's about it. I really wanted to love this liner, but I just don't. The possibility of adding up to 25°F to my sleeping system was very appealing! Especially as I was gearing up for test #1 in -25°F outside temperatures. At ~14 oz, this is a bit heavy, but I was willing to bring it along if it added warmth. Easy enough to get completely inside with my medium build 5'1"… Full review
