Product Description

Upgrade your sleep system with our premium Sleeping Bag Liner — designed to add comfort, warmth, and versatility to any adventure. Available in two performance fabrics, each liner enhances your sleep setup while remaining lightweight and packable.

Choose soft, stretchy knitted polyester for flexible comfort that moves with you through the night, or ultra-soft TENCEL™ lyocell for a smooth, sheet-like feel that naturally wicks moisture during warm, humid conditions. Both options provide breathable comfort and boost your sleeping bag’s warmth.

Use it on its own as a lightweight sleeping bag for summer nights, or secure it inside your sleeping bag using the built-in snap loops for added warmth and stability. A drawstring cinch top helps retain heat, while the rounded foot box keeps your feet comfortably enclosed.

Weighing just around 11 oz and packing down small, this liner is an easy addition to any backpacking, camping, or travel kit.
