Given that cycling is often equal parts cunning and strength, the pros use Kask's Protone Helmet to keep their strategic organ in top shape so it can effectively direct their energies when frantic finales send all the blood rushing to the legs. In-mold construction polycarbonate shell over EPSOcto fit cradle and adjustable chinstrap14 Large air ventsEasy-clean ECO chin strapCoolmax paddingIncredibly aerodynamicWeight: 230gTactical engines of the pro's are protected by an in-mold construction of a polycarbonate shell bonded with an EPS foam body, all of which is built on a frame designed to let the helmet absorb impact while still maintaining enough structural integrity to see you safely through the duration of a crash. While safety is a helmet's first (and usually last) job, there are certain benchmarks that today's industry expects top-end protectives to meet. The current front runner in this category is aerodynamics, and the Kask ran the Protone through the expected wind-tunnel paces in order to design a model that dodges the wind whether you're head-on in the drops or in virtually any other cycling posture imaginable.The second consideration is cooling, and unlike many of its competitors, the Protone doesn't sacrifice ventilation for aerodynamics. In addition to the immediately obvious vents and rear exhaust port, the Protone incorporates Coolmax padding. Coolmax padding equates to more efficient moisture transfer and evaporation to complement your body's natural cooling process. They're also antibacterial, removable, and contribute to the comfortable, personalized fit of the floating Octo Fit cradle and corresponding ECO Chinstrap.
