The compression short can be machine washed after removing the D3O pads—wash on cold or warm and hang dry. The D3O pads themselves should NEVER be machine washed or exposed to hot water. Hand-wash pads only with mild soap in cool water, rinse thoroughly, and air dry flat at room temperature. Machine washing or hot water can permanently alter the smart foam's rate-sensitive properties, reducing its impact protection. This is the main maintenance difference from EVA foam pads, which are generally more wash-tolerant.
