The Merit Spherical is the ideal choice for fast, flowy trail riding and hard pedaling. With Spherical Technology, it offers more comprehensive performance and protection with the combination of a Mips® brain protection system to redirect rotational impact energy. Plus, separate inner and outer liners featuring Progressive Layering help manage high- and low-speed impacts. Massive Wind Tunnel vents are combined with channels in the EPS foam liner, creating amazing airflow through the helmet to exhaust heat out, even on long, hot climbs. Fit and stability adjustments are fast and easy with the Roc Loc® Trail Air fit system, and plush Ionic+ padding provides exceptional sweat absorption while combating odor with permanent antimicrobial performance.

  • Spherical Technology
    • Spherical Technology's Ball-and-Socket design, power by Mips®, helps redirectimpact 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.
  • MIPS®-Equipped
    • All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Integrated Mips®-equipped helmets is to reduce rotational forces while enhancing fit and comfort by combining the Mips slip plane with the helmet's adjustable fit system. 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.
  • 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, lower-speed impacts.
  • 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.
  • Roc Loc® Air Fit System
    • This revolutionary fit system adds a new dimension to helmet perforamnce 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.
  • Wind Tunnel Ventilation
    • 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.
