Developed, designed, and tested by mountain bikers in close collaboration with three-time downhill world champion Greg Minnaar, the Oakley MTB Helmet DRT5 MIPS gives you the confidence to conquer even the toughest descents. The helmet's integrated MIPS Brain Protection System shields your head from multi-directional impacts, while the BOA 360 Fit System with highly elastic properties ensures an optimum fit and seamless compatibility with your goggles. The sweat-absorbing silicone strip channels sweat away from your eyes, keeping your goggles smudge-free. The six-position adjustable visor with over 60° of total adjustability allows you to store your goggles in a forward-facing position, and the rear retention hooks offer secure storage for your eyewear. Additionally, 13 ventilation ports ensure that you always keep a cool head. Certified according to (US) CPSC 1203, (EU) EN1078, (AU) ANZ2063, this helmet is a reliable protection choice for serious mountain bikers.
