If you like to rough it in foreign countries, or use very basic hostels then you might like the DreamSack™. Unlike cotton slips, this baby is made from silk and folds up really small and weighs just a few ounces. Also, silk is way better than cotton when you’re traveling; it keeps you cool in the summer, warm in winter and dries in minutes. At 93 inches long, it has a 39″ opening down one side with 5 tabs to close and a pocket to stick the pillow inside. Available in various sizes, they can be hand or machine washed, in cool water on gentle cycle with mild soap. There’s one that’ll line a sleeping bag, too. Keep a layer between you and any bugs! http://www.yaladesigns.com/travel
