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

Sea to Summit Reactor Thermolite Liner

rated 4 of 5 stars Warm bag liner for backpacking or traveling. I like this bag liner. It's tough and it's warm. I have used this on many occasions, and it has definitely extended my sleeping bag's comfort zone well into the shoulder seasons. It also makes ventilation easier in a sleeping bag: with this on, you can unzip the bag a little more to get air, without also getting a chill. One of my few complaints about it are that the material gets along too well with baselayers. It slides easily around inside the bag,… Full review

Coleman Stratus Fleece Liner

rated 3 of 5 stars This liner will add warmth to your sleeping bag without breaking the bank. Unzipped, it can also serve as a blanket. Nothing special here — it just gets the job done. I have had this fleece sleeping bag for over a year now. I originally got it because I don't have a winter sleeping bag, and so I wanted to make my current three-season bag warmer for a winter camping trip. This has turned out to be a pretty good purchase for me, as I've used it for more than just winter camping. Let's start with… Full review

The North Face Liner Bag

rated 5 of 5 stars OK, so this liner holds your core heat in and keeps the dreaded cold drafts out. I live on the Gasconade River in Pulaski County, Missouri. On my property we camp out a lot near the river. The temperature drops 7 to 9 degrees lower near the water's edge, so packing the right gear is a must for comfort and safety. Protecting your core is a must. Maintaing your body heat can make the difference in an OK overnighter or a great comfortable warm night's sleep. It sucks to be cold, so listen: buy this… Full review

Equinox Vapor Barrier Liner

rated 4.5 of 5 stars This product is well constructed and performs extremely well. It is lightweight and well worth the additional weight in the winter setting. I have ventured into winter backpacking and after my first three-day trip and an extra 10 pounds to my pack gained from my sleeping bag a barrier was in order. Originally going to make one, but this one made of the same material I had gotten design for and I could not make it for that price. Well constructed and keep my bag dry and keeps me dry and warm. Compared… Full review

Sea to Summit Reactor Thermolite Liner

rated 5 of 5 stars True-to-spec 15°F of added warmth and lightweight make this bag liner a winner. It's better than my old silk bag liner in that it's lighter and the moths don't like it. I'll start by saying this doesn't seem to be a true "mummy" liner in that it doesn't have the traditionally small mummy footbox. That really doesn't matter — what matters most is that it's warm! In fact, I can't believe how warm it is and I'd swear it adds more that 15° F to your bag. I thought I liked my old silk bag liner even… Full review

Cocoon CoolMax MummyLiner

rated 4 of 5 stars Great product, aided in my successful thru-hike of the Appalachian Trail 2012. I don’t know why anybody would go without one of these, even if it’s not this particular brand. Basically, you use this as a liner for your sleeping bag. It will add 5-10 degrees for when it’s cold, or you can just sleep in this by itself for when it’s super hot. One of the more important things too, is that you can simply wash it, rather than attempting to wash and potentially ruining your sleeping bag. The material… Full review
