The Dimir Ultralight Polar Fleece Sleeping Bag Liner is the versatile, packable sleep layer that belongs in every camper’s kit. Made from soft polar fleece in a mummy-style cut, it delivers warmth and comfort in temperatures above 15°C when used alone — and adds a meaningful warmth boost when slipped inside a heavier sleeping bag for cooler conditions. At 180 × 80 cm, it fits adults up to 1.8 m comfortably. The mummy shape minimizes cold spots and keeps the liner in place throughout the night, while the ultralight construction adds almost nothing to your pack. Whether you’re backpacking, camping, or using it as a tent bed mat, this liner delivers comfort without compromise.
