Including reflective accents, a lock port for securing the helmet with your bike or a bag when you’re on the move, and a TPU cycling cap-style visor that accents your style without compromising ventilation. The Merit™ Spherical is a high-performance trail riding helmet built around the ball-and-socket design of Spherical Technology™ to provide amazing ventilation, deep coverage and luxurious comfort.
Helmets with Spherical Technology offer 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.
The 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 odour with permanent anti-microbial performance. With all of these features, it's an ideal choice for fast, flowy trail riding and hard pedalling.
