The Giro Hex Mountain biking helmet includes rugged design, huge efficiency and impressive value. Features the new Roc Loc 5 fit system. After more than ten years of refinement, this ground-breaking fit system supplies a totally special usage experience with an unmatched level of convenience, stability, adjustability and weight cost savings. With Roc Loc 5, you can quickly dial-in both fit stress and adjust vertical position with a single hand. Simply twist the dial for a tighter feel on challenging terrain, then back it off a notch and relax across the flats or a warm climb. Even with these remarkable features, Roc Loc 5 is still 40-percent lighter than its popular predecessor, Roc Loc 4. Roc Loc 5 systems is: 1) Micro Dial. The heart of the Roc Loc 5 is this ratcheting, micro-adjusting dial. A basic, two-finger twist of the Micro Dial opens or closes the retention system and each click is audible. 2) Three-Position Vertical Fit - It's never ever been easier to change vertical positions and tweak fit. We included a three-position bracket that includes 15-millimeters of precise up/down activity. Like the Micro Dial, this system can be adjusted without removing the helmet. 3) Carefully crafted ergonomic arms are formed to be as comfortable as possible, yet work flawlessly with Giro eyewear (what we call Super Fit engineering). 4) Dual Pods - These two panels are developed to firmly understand the back of your head while conveniently nestling the occipital lobe. Strap management - with Roc Loc 5, your helmet straps are woven through the fit system, so they are constantly in the best position. Complex Internal Design - Dozens of little parts interact effortlessly to offer remarkably easy to use modification. Very little and Light, yet Strong - Although this fit system is 40 % lighter than its predecessor, it's much stronger. In testing, Roc Loc 5 carries out flawlessly, even after 6,600 cycles (equivalent to 3 years of riding with 3 round trips per day).
