Sleeping Bag Liners, Covers & Blankets

Sleeping bag liners and camping blankets that add warmth, comfort and a layer you can actually wash. Silk, fleece and polycotton liners from Snugpak, Highlander and Mil-Tec, alongside packable blankets for camp.

Start with what a liner is for. A liner slips inside your sleeping bag to do two jobs: add a few degrees of warmth, and keep the bag itself clean, since a liner is far easier to wash than a full bag. Polycotton and silk-mix liners are light and pack down small, ideal for summer and travel, and a fleece liner adds the most warmth and turns a summer bag into a three-season one. The Snugpak TS1, Paratex and Silk Mix cover the range from featherweight to genuinely warm.

Blankets earn their place too. The Kelty Biggie is an oversized camp blanket for throwing over two people at a fire, the Snugpak Jungle Blanket is a light packable layer, and the Highlander Thermo survival blanket is the emergency one that lives in the rucksack lid. A compression sack squeezes any of them down to fit a packed bag.

Match the liner to the season and how you travel. For the bag itself see Sleeping Bags, add a sleeping mat for warmth from the ground, and for a bivvy bag to sleep out under a tarp see Tarps & Bivi Bags.

Frequently Asked Questions

What does a sleeping bag liner do?

A liner adds a layer of warmth inside your sleeping bag and keeps the inside cleaner, since it is far easier to wash than the bag itself. A thermal or fleece liner can add several degrees of warmth.

Which liner is warmest?

Fleece liners add the most warmth and are the best choice for cold weather. Silk-mix and polycotton liners are lighter and pack smaller, better for summer, travel and hygiene rather than heat.

Can a liner extend my sleeping bag's season?

Yes. Adding a fleece or thermal liner to a summer bag can push it into three-season use, a cheaper and lighter option than buying a second bag.
