The ideal helmet for city commuters. We like to think of the Sundown as the collection's Swiss Army Knife: a lightweight, versatile multitool that can be used for any task. When the weather is pleasant, wear it open-faced; when you want to accelerate, just flip down the interior visor.Pull up the visor in the rain and you'll be able to ride in comfort! The helmet comes in two ergonomic shell sizes and is constructed of a fiberglass shell called "RQ LIGHT" with a multi-density EPS lining. Features include an integrated retractable visor system, premium leather detailing, 'RQ XXL' retro rubber trim, microtech fleece comfort lining that is detachable and washable, and a fast release microlock adjustable chinstrap with Microtech fleece padding that is approved by ECE-R22.06.
