Machine wash in a washing machine WITHOUT AN AGITATOR, agitators are likely to cause damage to your gear. Oversized bags require oversized machines, you may need to go to a laundromat to wash your larger bags. Wash on a warm, gentle cycle. Use gear specific soap, we recommend Nikwax Down Wash Direct. Rinse twice. Tumble dry low heat with clean tennis balls. Finish by drying on high heat in 5 minute intervals to loft down. *Allow to cool between intervals to avoid damage to shell*. Do not use fabric softeners. Do not bleach. Do not iron.
