The Anon Prime MIPS Snow Helmet offers a hybrid shell design that combines hardshell durability with the lightweight feel of in-mold construction for a helmet that is incredibly light and tough. The 360 BOA Fit System offers quick, micro-adjustable fit with the turn of a dial. The MIPS (Multidirectional Impact Protection System) helps reduce angled impact forces for increased crash safety. Adjustable ventilation gives you one-handed control over all 23 vents, so you can fine tune your temperature depending on the weather and activity.
