The Transition Hardshell may look like another skate helmet, but its in mold technology and EPS foam actually make it closer in relation to Fox Racing's Flux. This means that the Transition is actually lighter than the alternatives, and better suited to mountain biking. A tough ABS outer and expanded polystyrene core absorb impact and keep your gray matter in the factory case, while 12 vents guide air into and through the Transition for all day comfort. Fox Racing uses Inset chin straps to anchor the webbing directly into the EPS shell. This improves strength, and further reduces bulk and overall weight. Fox Racing's Transition Hard Shell Helmet passes CPSC safety standards.
