Recent Sleeping Bag Liner Reviews

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

Cocoon Silk MummyLiner

rated 4.5 of 5 stars Lightweight, adds warmth. Was not sure this would work out but it DOES keep me warmer and keeps bag cleaner and is very lightweight and compact. I got the green color. Full review

Sea to Summit Reactor Thermolite Liner

rated 5 of 5 stars This thing will add warmth and extend the life of your sleeping bag. This thing always goes with me, no matter which sleeping bag I'm using, because it adds the extra warmth or helps regulate my sleeping comfort temperature. It also does a great job in keeping my body odor or oils from getting on to a very expensive bag and thus extending the life of your sleeping bags. Full review

Sea to Summit Reactor Plus Thermolite Liner

rated 4.5 of 5 stars Really warms up a bag when you are on the cold edge of what your sleeping bag can handle. This bag liner is amazing. It really warms up the bag. I was camping with this and my Marmot Atom (40°) and the temps got down into the high 30s. I woke up in the middle of the night chilled so I slipped into this and immediately felt more warmth. Not long after I was getting really warm and had to vent my sleeping bag. I would never guess such a thin fabric would hold in so much heat. The bag liner packs… Full review
