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.

Note: We recommend you try helmets on before buying. Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.
