When you spend all day on the slopes, you may find that it doesn’t take long for your balaclava to get smelly with your sweat. Naturally, you are going to eventually want to clean your ski mask. Some can be thrown in your washing machine and dried with your regular clothing. Others, like the Beardski, require handwashing only. You will want to refer to the manufacturer’s instructions on the particular ski mask you choose to order. When in doubt, handwash.
