If you're tired of trying to clean the inside of your sleeping bag and it's constantly getting dirty, a liner will be a great solution. 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.FEATURES• Brushed polyester or poly-cotton options• #5 Separating zippers• Standard stuff sackSPECS
