The Agilis is perfect for riders looking for a helmet that combines an airy design with a bit more coverage and many performance features aimed at road and multi-surface riding. A comfortable and secure fit is achieved thanks to the adjustable Roc Loc 5.5, which combines fit and positioning adjustments. The outer Hardbody shell extends to the inside of the helmet and is molded from durable polycarbonate, permanently fused to the EPS foam liner using the In-Mold process, increasing durability and ventilation without adding bulk. Features: Wind Tunnel Ventilation System: Giro helmets are developed using their proprietary Wind Tunnel ventilation system. This elaborate design combines active vents in the helmet shell with exhaust channels inside the helmet, driving fresh, cool air over and around the rider's head while forcing heat and stale air out. It's the most effective cooling system available, and you'll feel the difference every time you ride. In-Mold 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. Roc Loc 5 Fit System: The industry benchmark in comfort, stability, adjustability, and weight savings. In addition to enhancing the fit and comfort of the helmet, Roc Loc 5 allows you to easily customize the fit tension and the fore-aft tilt of the helmet in seconds with a single hand. And because it's lighter than comparable systems, it's the ultimate in skull-hugging luxury.
