Using the Endura Hummvee Helmet is easy. First, put it on your head and adjust the chin strap with the twin - strap adjusters until it fits snugly. You can use one hand to make quick adjustments while riding. If there are bugs around, the integrated bug net will keep them away. For cleaning, simply remove the antibacterial and fast - wicking padding. Wash it gently with mild soap and let it air - dry. When not in use, store the helmet in a cool, dry place. Avoid exposing it to direct sunlight for long periods as it may damage the materials. Also, check the helmet regularly for any signs of wear and tear. If you notice any cracks or damage, it's time to replace the helmet for your safety.
