The Capitan MIPS is Black Diamond&';s bomber, ultra-durable helmet, featuring added coverage on both the sides and back and MIPS tech, while maintaining a sleek, cradle fit for all-day comfort. The added MIPS (Multidirectional Impact Protection System) technology. The MIPS system is designed to protect against the rotational motion (or kinematics) transmitted to the brain from angled impacts to the head. This added protection system has been proven to reduce the rotational violence to the brain by absorbing and redirecting oblique impacts to the helmet. With a 2-piece ABS shell construction, a fusion of EPP foam and an EPS foam puck, the Capitan meets the proposed UIAA increased side and back protection requirements, while the vents provide ample breathability when temps heat up. A low-profile suspension system dials in the fit, and the integrated headlamp clips with an elastic keeper on the back secure your light so you can push through the night.
