ArcOne® produces a complete array of passive upgrades. Our specially designed cover plates are lightweight, but still hold up to the highest standards. We pack them individually so you only need to buy what you need. If you own a single shade filter and need a slightly darker shade for comfort, our passive shade 1 & 2 upgrades will meet your needs. ArcOne® helmets must use ArcOne® cover plates due to the helmet designs. Our cover plates may be used with all other manufacturer helmets.
