Travelers, campers, and anyone who values clean bedding - this EXERMIL cotton sleeping bag liner is about to become your new best friend. Made from 100% soft, breathable cotton that feels amazing against your skin, this liner features full-length zippers on three sides so you can get in and out from any direction. When fully unzipped, it transforms into a giant 87x88 inch bed sheet - perfect for covering questionable hotel bedding. The French seams prevent fraying and the included pocket keeps your pillow in place. At just 1.58 pounds, it packs down small into the included carrying bag, taking up minimal space in your luggage. The cotton adds about 10-15°F of warmth when you need it but stays cool in warmer conditions. Whether you're backpacking through hostels, camping in questionable conditions, or just want that extra layer of cleanliness in hotels, this liner has you covered. It's machine washable and dries quickly, making maintenance a breeze. Seriously, this might be the most versatile travel item you'll ever own.
