The Naturehike Ultralight High-Elastic Sleeping Bag Liner is the compact, featherlight upgrade your sleeping setup has been waiting for. Weighing just 360g and packing down to a tiny 19 × 9 cm, it adds almost nothing to your pack while delivering a meaningful boost in comfort and hygiene. The 80% polyester / 20% high-elastic fiber blend stretches to accommodate your sleeping position without bunching or restricting movement — a improvement over rigid cotton liners. Rated for temperatures from 5°C to 15°C, it works as a standalone bag in mild weather or as a liner inside a heavier sleeping bag to extend its temperature range. At 200 × 80 cm, it fits adults up to 1.8 m comfortably, and the splicing zipper lets you connect two liners for a double configuration.
