Using your Lost Coast 30 Degree Down Sleeping Bag is a breeze. Just unzip the anti - snag zipper and crawl inside. The roomy design allows you to move around a bit while still keeping you warm. You can use the internal stash pocket to keep things like your phone, keys, or wallet close and warm. When it comes to maintenance, make sure the bag is completely dry before storing it. If it gets dirty, follow the care instructions on the label. Avoid sharp objects that could tear the ripstop shell and liner. When packing, try to roll it up gently to keep the down fluffy. This way, your sleeping bag will last you many camping trips.
