Lightweight, adjustable and won't slide off like bands or scarfs, plus won't pull hair like tight bathing caps do. These ear muffs are designed to keep professional ear molds, ear plugs or wax molds in place. The inner soft foam lining contours to the shape of the ear, gently holding the ear mold where it belongs, and the outer shell has straps with an adjustable buckle for sizing. Foam snaps out of the shell for quick drying.
