Using this Arai Helmet Bag Backpack is a breeze. First, if you're putting in a large helmet like the VX - Pro'4 or XD - 4 with a peak, just turn the helmet around to fit it in easily. You can place your helmet shield in the double shield pouch. When you want to carry it, you can either hold it by hand or pull out the padded shoulder straps from the zippered compartment and wear it as a backpack. For storage, keep the bag in a dry place away from direct sunlight. To clean it, use a soft cloth and mild soap to wipe the exterior. Make sure to fully dry it before storing to prevent any mold or mildew growth. When not using the shoulder straps, always tuck them back into the zippered compartment to keep them safe and the bag looking tidy.
