Giro Merit Spherical Helmet matte metallic black/anodized lime

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.

MIPS Spherical
MIPS Spherical is a refinement and evolution of the Multi-Directional Impact Protection System (MIPS). With this sophisticated design, two layers of EPP foam fit together like a ball-and-socket. This system helps protect the brain from rotational energy by allowing up to 10- to 15- millimetes of relative motion between the helmet and head during the first milliseconds of an impact.
