Recent Sleeping Bag Liner Reviews

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

Sea to Summit Reactor Thermolite Liner

rated 5 of 5 stars An excellent addition for a 3-season sleeping bag to convert it for cooler temperatures and at altitude. It is lightweight and compact and works perfectly for late spring camping in the mountains. This lines worked perfectly in my North Face 40-degree bag to ensure comfort and warmth while backpacking in early June in elevations ranging from 8,500 to 11,000 feet.  The length was just right and provided sufficient width for normal movement during sleep.  It added at least 5-8 degrees of warmth… Full review

Sea to Summit Toaster Fleece Liner

rated 3 of 5 stars The Sea to Summit Toaster fleece liner is a bit bulky and heavy but can be used in a few different ways. I ended up using it more as a summer bag and a bag cover in the winter. Due to its size and weight I see it being used more for recreational camping rather than long backpacking trips. I picked this liner up at a local outfitter for a week long winter backpacking trip I was planning this past year. I was expecting single digit temps and blistering winds, and since I get cold really easy I was… Full review

Sea to Summit Reactor Extreme Thermolite Liner

rated 4 of 5 stars Provides a 7-9° F increase inside the bag. For the size and weight, I would recommend it as a comfort item, if you can fit it into your budget. I was very skeptical about the +25 degrees claim of the Thermolite Reactor Extreme so, I set up this little experiment to see just how well the liner worked. Because sleeping comfort is such a personal thing, I will try and provide as much information here as possible so that you can make your own informed decision. I used a sleeping bag rated at the current… Full review

Sea to Summit Reactor Extreme Thermolite Liner

rated 2 of 5 stars Don't count on this liner for an additional 25 degrees of warmth, or even 15 degrees. Very disappointed in this liner. I had my 30-degree bag and knew I'd be on the borderline temp wise. I'm a cold sleeper, and was excited to try this out. There is no way this 'increases warmth by up to 25 degrees." Thankfully at the last minute tossed my fleece bag liner in the car. At 3 a.m. I finally gave up on the Reactor and switched to the fleece — and slept toasty warm for the rest of the night. I was surprised… Full review

Sea to Summit Reactor Thermolite Liner

rated 2 of 5 stars Who doesn't want to push their gear a little without having to purchase another sleeping bag? Adding 15° to your setup just may keep you from adding another bag. If that's your goal and you want an additional warm weather option you might think the Reactor will work for you. In my experience the Reactor falls well short of the advertised performance. Being a budget conscious guy I really wanted the Reactor to work to extend my hammock TQ to the 20's and give me a stand-alone option in the 60s,… Full review

Columbia Omni-Heat Sleeping Bag Liner

rated 4 of 5 stars Magical little silver dots in a lightweight package in a 10 oz. large grapefruit package promise added warmth. And those little silver dots pretty much deliver as advertised. In my last overnighter I was comfortable at 55° using a 40° under quilt in my hammock. After a little experimentation I'm pretty convinced that those little silver dots are a welcome addition to the bag liner. I really hate to perspire while I sleep. It makes for a long night that usually ends around 4:30 for me and makes… Full review
