ALPS Mountaineering Rectangle Liner Sleeping Bag Charcoal. Using a liner will eliminate all the dirt that gets transferred from the great outdoors to your sleeping bag. Liners are easy to remove and toss into the washer when you get back home (a lot easier than trying to clean the whole inside of your bag) If you ever need a light cover in the summertime the liner can double as a sheet as well.
