A Travel Sheet is an extremely lightweight and roomy sleep sack or sleeping bag liner. These versatile sheets are excellent as a warm weather sleeping bag or a rectangular sleeping bag liner. Compact and lightweight, Travel Sheets are ideal to bring to hotels, youth hostels, alpine huts, boats, planes, trains, or anywhere else you might travel. Egyptian cotton is a rare, long fibered cotton that is spun into a fine yarn. The result is a very lightweight and soft, yet durable fabric. COCOON Travel Sheets made of Egyptian cotton are substantially lighter and more compact than those of regular cotton. A great compromise between regular cotton and silk and ideal for the price conscious buyer who wants to buy an affordable, high quality product for his/her outdoor adventures!
