Upgrade Your Adventures With A Sleeping Bag Liner

Boost warmth by up to 8ºC, keep your sleeping bag cleaner, and improve your sleep quality – this Sleeping Bag Liner is a small upgrade with big benefits. The ultralight synthetic knit fabric traps heat efficiently while still remaining breathable and moisture-wicking, so you stay warmer and sleep better in the wild. If you’re camping out in cool to cold conditions, then this sleeping bag liner is a lightweight add-on to your sleep setup that is worth every gram.

The Best Sleeping Bag Liner For Camping, Travelling & More

Made from a high-quality knitted polyester fabric, Alton’s Sleeping Bag Liner is soft, stretchy and breathable – and way more comfortable than sleeping directly on your sleeping bag inner shell. Weighing just 450g and packing down small, this sleeping bag liner was designed for camping and hiking, but functions just as well as a lightweight liner for travelling or sleeping in shared spaces.

New & Improved Sleeping Bag Liner Functionality

Our Sleeping Bag Liner has a full-length zipper along the outer edge that aligns with the zipper placement on our best-selling sleeping bags. This feature makes it easier to get in and out of your sleeping bag and liner without disrupting your sleep system (and waking everyone up in the process). In cold conditions, the drawcord hood can be tightened to increase heat retention.

Stay Clean and Sleep Better With A Sleeping Bag Liner

Using a Sleeping Bag Liner helps protect your sleeping bag from contaminants like sweat, dirt, and body oils that build up over time. This maintains insulation performance for longer and can extend the lifespan of your sleeping bag. It’s easy to wash your sleeping bag liner after each trip – simply hand wash in warm water with gentle laundry detergent, rinse thoroughly, and hang or lay flat to air dry away from direct sunlight.
