We advise only using a mild soap, lukewarm water and a non-abrasive microfiber cloth to clean the outer shell of your helmet, the inner padding, and the retention system. The U-Shaped ear pads are attached using Velcro and can be easily removed for cleaning. After cleaning allow the interior and ear pads to air dry in a well-ventilated area for 24 hours before reattaching them to the helmet. Never use dryers, or place near heaters or other heat sources to speed up the drying process.
