What Our Gearhead(R) Experts Are Saying: "I switched to the Driver Prime for storm days and never looked back. The Sigma photochromic visor pops contrast and flips up fast on the lift, Mips adds peace of mind for angled falls, and the BOA fit dial locks the helmet in without pressure points. It's clean, quick, and glasses-friendly for OTG comfort."We ride clearer and think less with the Driver Prime Sigma Photo Mips Helmet. The fully integrated, magnetic Sigma photochromic visor boosts contrast in variable light and flips up in a snap for fresh air or lodge stops-no fumbling with separate goggles. A hybrid shell keeps weight down without giving up durability, while Mips technology adds protection from rotational impacts when falls don't go to plan. A micro-adjustable BOA Fit System dials a secure, even wrap you can tweak with gloves on. Static ventilation helps manage heat on high-output laps, and the visor's OTG-friendly shape accommodates prescription glasses comfortably. From bluebird corduroy to storm-day tree runs, this visor-helmet combo streamlines our kit and sharpens our view of the line.
