Giro Merit Spherical MIPS Bike Helmet

Hardshell with In-Mold Hardbody™ Lower Wrap: The two-piece shell combines a tough outer hard shell with a polycarbonate lower shell permanently fused to the liner for durability without excess weight.

Progressive Layering™: Two different materials are used to manage impact energy: One layer is EPS, which is well suited to high-speed crashes. The other is a lower density EPP foam with rebound characteristics that address the more common, low speed impacts.

Roc Loc® Air DH: Adjustable fit system enhances the helmet's comfort, stability, and interior ventilation while reducing the chances of accidental adjustment.

Wind Tunnel™ Ventilation: Giro helmets are developed utilizing the proprietary Wind Tunnel™ ventilation system, which combines active vents with internal exhaust channels that thrust cool, fresh air over and around the riders head-while forcing heat and stale air out. This significant increase in air channeling makes a difference that riders will immediately feel and appreciate.

MIPS® Spherical: MIPS® Spherical is a pair of foam layers that work like a ball and socket to redirect impact energy in a crash. The system uses two distinct layers of foam within the helmet, rather than a single layer of foam and plastic liner. One layer is EPS, which is well suited to high-speed crashes. The other is a lower density EPP foam with rebound characteristics that offer protection in low speed impacts.

Adjustable Moto-Style Screw-In Visor: This visor features an adjustment mechanism that lets you move the visor up and down in indexed steps. These steps include three riding positions plus a high position for goggle storage above your brow, allowing you to easily adjust your visor with one hand while riding.

Complies with the US CPSC Safety Standard for Bicycle Helmet for Persons Age 5 and Older
