Meet the Brentwood. It's the thinnest, lightest, lowest profile bike helmet available for adrenaline-pumping sports like skateboarding, biking, inline skating, snowboarding and skiing. Tough, PVC shell is fused with liquid-injected, high-impact foam to protect your grey matter from the worst blows. Channeled vents keep your head cool while the detachable visor keeps you looking cool. Sink Fit design fits lower for better protection and accommodates sunglasses or goggles.
