Yes, our organic cotton masks are preshrunk and stand up well to frequent machine washing and drying. We recommend that you wash them before using them the first time. Machine wash in cold water with mild detergent. Do not use bleach or fabric softener. Dry flat or on a line or in the dryer on a medium to low setting.
TIP: Turn your mask inside out and tie the cotton cord together in a loose knot before washing to avoid tangling.
