Shred Optics' Slam Cap Helmet exceeds safety standards for both snowboarding and mountain biking, so you can ski all winter and bike all summer with the same brain bucket. Underneath the tough, dent resistant in mold shell, Slytech's NoShock technology dissipates impact forces multi directionally by spreading the force laterally and limiting the transference through the helmet to your head. For you, this means hopefully you won't see new colors the next time you land headfirst off a jump. Shred Optics bonded Slytech's NoShock to soft EPS foam and lined the whole helmet in smooth, removable, odor resistant X Static fiber for comfort. There's also a foldable vent cap that closes off or opens each vent for customized airflow, and multiple switches for the top vents. A fitting dial with three straps for a customized fit up top and at both sides. IceDot identifying technology helps others identify your knocked out self by accessing the info you provide online prior to any emergency.
