HardnutZ mountain bike helmets are the peak in lightweight, aerodynamic, all-terrain protection. Rocking a PC outer shell with high-density, impact-absorbing inner EPS and 360-degree ventilation, you can keep a cool head and step-up your off-road activites during even the toughest trial or session. The Advanced Rear Retention Adjustable Fit System and double-thickness strap comfortably prevent slipping and the pro design visor lets you focus on your flow. Back on the cycle paths and tarmac, the 19 panels of clean, colour-coded, hi-vis 3M Scotchlite reflective vinyl will safely ensure maximum visibility under street lamps and car headlights. Come on, show 'em what you're made of – get into gear, pimp your nut and put your mettle to the pedal!
