Anyone who spends more than one night in the great outdoors should own and carry a sleeping bag liner. Sleeping bag liners don't just add to the life of your sleeping bag by helping you to keep it clean, but they can also add warmth and moisture-wicking capabilities to your bag’s rating. Most liners add 5 to 10 degrees to the rating of the bag, while liners exist that will add up to 25 degrees to the rating. We also love sleeping bag liners for traveling - if you're staying in a hostel and want to give yourself an extra layer of protection, or just crashing on a buddy's sketchy couch, you'll love this lightweight addition to your travel gear.

Even better, many of the available types of sleeping bag liner do more than just keep you warm and clean. The Coolmax Adaptor Traveller w/Insect Shield offers an insect repellent treated into the liner itself so that you can sleep more comfortably in warmer temperatures. The Reactor Extreme Thermolite Liner adds up to twenty-five degrees of warmth for those coldest nights. And if pack space is an issue, the Reactor Plus Thermolite Liner offers a more compact size and weight while still providing up to twenty degrees of protection.

Stay Warm, Stay Active



Whether composed of specialty Thermolite fabric, cotton, fleece, or even ripstop silk, the extra layers of protection are ideal when you have travel on the mind. Campers get added warmth and protection from the inevitable dirt dragged in. Backpackers can use their liners for multiple purposes while on the trail, especially since there isn’t likely to be a lot of extra space for carrying bulky fabrics. Sleeping bag liners are also a must for anyone who will be backpacking through Europe and will be frequenting hostels. Slide your pillow into the pillow case, crawl into the liner, and sleep soundly no matter where you are.

To get the most out of your sleeping liner, you’ll also want to choose a durable, low-temp sleeping bag to go along with it. Together, the layers will do wonders in keeping you comfortable.
