The Giro Switchblade MIPS full-face mountain bike helmet is built for unreal downhill performance with maximum safety and comfort. The ROC LOC Air DH Fit System adds a new dimension to helmet performance by enhancing cooling, as well as fit comfort and stability. Using a patented design that suspends the helmet just slightly off the top of the skull, Roc Loc® Air DH allows cool airflow to pass directly over your head, improving the performance of vents and internal channelling that let heat out of the helmet. 

The Switchblade is built to be incredibly practical, the chinbar is easy to remove, just push the buttons and rotate up and you’ll enjoy the freedom. While the bumper around the dial helps prevent accidental adjustments if your helmet contacts your backpack or neck brace—all while keeping you cool. The full-cut style of this downhill helmet gives you an aggressive look and provides ASTM Certified coverage even when you remove the chinbar. The Giro Switchblade MIPS is unique in that it is one of the few downhill specific helmets with a removable chin bar and endless possibilities for your riding.

Features

Roc Loc Air DH Fit System: This revolutionary fit system adds a new dimension to helmet performance by enhancing cooling, as well as fit comfort and stability. Using a patented design that suspends the helmet just slightly off the top of the skull, Roc Loc® Air DH allows cool airflow to pass directly over your head, further enhancing the performance of vents and internal channeling that exhaust heat out of the helmet. Fit and feel adjustments mimic the Roc Loc 5, allowing you to easily custom tune fit tension and fore-aft tilt of the helmet in seconds using a single hand.

MIPS: All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's MIPS equipped helmets is to reduce rotational forces. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider's brain in certain impacts.

Hydrophilic Padding: The Hydrophilic Pad can absorb up to 10 times its own weight in water, helping you manage sweat while riding. The pad retains moisture to prevent sweat from dripping into your eyes, and then dries quickly. The antimicrobial, X-Static lining helps to reduce odor, keeping your helmet fresh.

In-Mould Construction: In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.
