Cocoon Silk Bag/Travel Sheet
Urban sleeping bag
I’d like to recommend the Cocoon Silk Bag Liner/Travel Sheet. It works like a sleeping bag in hot weather. I’ve used it when staying at hostels as well as when couch surfing so people don’t have to hassle with sheets for me. It can be a sleeping bag liner, too. It’s light (6.3 ounces), packs down very small (5.5 x 7 inches – it comes in its own satchel) and is really quite comfortable.
