Campers and backpackers, listen up! This Cocoon Mummyliner Silk is one of those gear upgrades you'll wonder how you ever lived without. Made from premium quality silk with a cool checked pattern, this tapered liner fits perfectly inside your mummy-shaped sleeping bag. The silk is magical stuff - it feels cool in summer yet warm in winter, adapting to your body temperature throughout the night. It's incredibly lightweight and packs down super small, which is gold when you're counting every ounce in your backpack. The ripstop construction means it's more durable than regular silk, so you don't have to baby it. It adds about 5.3°C (that's roughly 9.5°F) to your sleeping bag's temperature rating, which can make all the difference on chilly nights. But here's the real win - it keeps your sleeping bag clean from sweat, dirt, and oils, so you don't have to wash your expensive sleeping bag as often. Features include a drawstring hood, wide top opening, boxed foot end, and it's completely double-stitched for durability. At 241 x 90/56 cm, it fits most mummy bags comfortably. Easy to hand or machine wash and it dries quickly too. Whether you're backpacking, hostel-hopping, or just want extra hygiene in your sleeping bag, this liner is worth every penny!
