Using your Lost Coast 40 Degree Down Sleeping Bag is a breeze. Just unroll it at your campsite and get inside. The anti - snag zipper makes it easy to get in and out. To keep small things like your phone or keys safe, use the internal stash pocket. When it comes to maintenance, try to keep the bag dry. If it gets wet, dry it as soon as possible to prevent damage to the down filling. You can store it in a large, breathable bag to keep the down lofted. When packing it for a trip, roll it up tightly or stuff it into a compression sack. And remember, although it's durable, try to avoid sharp objects that could tear the shell and liner.
