THE POWER OF COOL
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.

📏Helmet Size Chart
Measure your head circumference with a soft tape ~3 cm above your eyebrows, around the widest point at the back of your head. Match the cm value to your helmet’s size band on the product page.
Match Size
Compare your cm number to the size band on the product page (e.g. 54–58 cm). If you fall between bands, size up.
Adjustable Dial
Once on, turn the rear adjustment ring until snug. The chin strap should sit flat with no slack — fine-tune the V-yokes around your ears.
