Zack W Below are the cleaning instructions for sleeping bags. 1. DO NOT DRY CLEAN. 2. Close zippers and Velcro tabs. 3. Machine wash in front-loading machine (DO NOT use machine with agitator, agitator could cause damage not covered under warranty) with cold water and mild soap (Ivory Flakes, Woolite, Sport Wash, Etc.) Not detergents. Down sleeping bags require a special down wash (Nikwax, Mcnett?s) that protects the oils on the down feathers/clusters. 4. Rinse thoroughly; double rinse to eliminate soap residue. 5. Dry in LARGE front loading dryer on low heat. Check occasionally on status. Too much heat can damage the fabric and fill. Using a small dryer can put a part of the bag too close to the heating element and melt part of the bag. This will not be covered under warranty. ***If after cleaning you notice clumps follow drying instructions above and use a few clean tennis balls to help break these up***
