Giro Merit Spherical Helmet

Engineered for serious trail riders, the Merit Spherical leverages advanced Spherical Technology with its distinctive ball-and-socket construction to deliver superior ventilation, comprehensive head protection, and exceptional comfort during demanding rides.

Built for aggressive trail pursuits, the Merit Spherical combines Spherical Technology with MIPS brain protection to manage rotational forces effectively. Progressive Layering in dual-density construction handles both high and low-speed impacts with precision. Strategically positioned Wind Tunnel vents paired with internal foam channels maximize airflow for sustained cooling on demanding climbs. The Roc Loc Trail Air system enables quick micro-adjustments for a secure fit, while Ionic+ padding delivers superior moisture management and odor resistance throughout extended rides.

• Spherical Technology's Ball‐and‐Socket design, powered by Mips helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. It also eliminates contact with hard plastic or slip‐planes against the skin.
• 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.
• Giro helmets with Progressive Layering use two different density EPS foam liners to address high‐ and low‐speed impacts for more comprehensive energy management.
• 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.
• 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 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.
• Giro helmets are developed utilizing our proprietary Wind Tunnel ventilation system. This elaborate design combines active vents in the helmet's shell with exhaust channels inside the helmet that thrust 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 a difference you can feel every time you ride.
• Integrated eyewear grippers help secure sunglasses.
• 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. The design allows you to easily adjust your visor with one hand while riding.
• The integrated rubber goggle gripper on the back of the helmet helps to ensure that goggles stay in place even when you're getting rowdy on the trail.
• Pure Silver is the secret ingredient that gives IONIC the power to provide natural, permanent odor protection to keep your helmet feeling fresh.
