The Protone is a an intersection of an aerodynamic design and a traditional road helmet. Kask put their best technologies into the Protone for an unparalleled aerodynamic helmet that suits for your need for speed. Looks and function aside, at its' core the Protone features an inner frame that is designed to break apart upon impact. This absorbs and defrays shock. Kask uses their Octo Fit rubber micro dial adjuster to distribute 180-degrees of equal tension. The floating cradle contact points work well with the internal gel pads to sit comfortably on any head shape. Coolmax inner padding and an eco-leather chin strap keep the Protone sitting comfortably on your head.

Right out of the box, the best helmet I've ever owned. I took it out of the box, it immediately fit with zero adjustment required. Love how the straps sit flush with my head, tons of adjust ability with the fit system. Lightweight and looks great!

Great helmet. I have been a Giro customer, Synthe MIPS, however I got so tired of having to replace the liner every month, Not so with this helmet. The lining is removable, easy to wash and dry and so much more substantial than the Synthe. It has a leather chin strap and an easily adjustable fit which complements the shape and size of the helmet perfectly. Great piece of gear and makes me happy to have discovered a product I can recommend.
