Smith Mainline MIPS Mountain Bike Helmet

MAXIMIZE VENTILATION
The well ventilated Koroyd® panels ensure consistent, engineered airflow whether riding or stationary. In addition, the Smith helmets feature internal air channels that combine with open intake and exhaust ports to maximize ventilation.

PRECISE FIT
Ultimate integration starts with the precise fit of the Smith goggle and helmet. Our helmets are designed to match the curvature of the goggle frame, eliminating "gaper gap" and allowing precise alignment between the helmet AirEvac and the goggle venting systems.

MAXIMUM AIRFLOW
Goggles fog when standard helmets trap warm, moist air in the goggle chamber. Smith's AirEvac ventilation systems generate maximum airflow and pull warm, fog-causing air out of the goggle. The warm air is allowed to exhaust out of the top of the goggle and begin its path through the helmet's AirEvac system.

KOROYD®
Koroyd® absorbs more energy on impact, offers better design flexibility and guarantees more efficient ventilation compared to materials traditionally used in helmet construction. The cylinders form a crumple zone and collapse evenly on impact. Thus, Koroyd® absorbs energy more efficiently and with less bulk than other protective materials on the market. Unlike traditional protective materials, Koroyd® cylinders absorb and convert more kinetic energy, while increasing airflow and reducing overall weight. Not all helmets are created equal.

MIPS®
The MIPS® Brain Protection System (BPS) is found inside the helmet, generally between the comfort padding and the EPS (a high-quality foam used to reduce energy). For certain impacts, the MIPS® BPS can reduce harmful forces transmitted to the brain. MIPS® stands for Multi-directional Impact Protection System.
