Equipped With
Multi-directional Impact Protection System (MIPS)®
MIPS® Brain Protection System is a helmet-integrated, low-friction layer designed to reduce rotational motion transferred to the brain from angled impacts to the head.
Universal Fit™
Giro’s Universal Fit helmets are sculpted to look good and fit great for almost anyone on their first try. By developing proprietary shell sizes based on specific customer groups and combining them with an easily-adjustable fit system, it’s easy for you to get the right fit straight out of the box.
In-Mold Construction
In-Mold Construction permanently fuses a light-yet-durable outer shell with the helmet’s impact-absorbing EPS foam liner, enhancing the strength of both parts. This fusion process reinforces areas around vents and ribs, creating a one-piece ‘exoskeleton’ that allows the helmet to be lighter, more durable, and better ventilated than helmets with shells that are fastened or adhered to the liner.
Roc Loc Sport
Roc Loc Sport fit system offers easy one-handed operation with a 7-centimeter adjustment range. With comfort similar to the Roc Loc 5, plus ponytail compatibility, the new Roc Loc Sport fit system brings premium function to sport level helmets.
