The Sweet Protection Switcher 2Vi Mips helmet builds on the 2Vi platform with a Mips layer shaped to the helmet's own geometry, reducing rotational motion in certain angled impacts. A multi-density EPS liner with Impact Shields targets protection in key zones, and hybrid hardshell-and-in-mold construction keeps the shell rigid without adding bulk. The rear dial opens and closes the vent system with one hand, and the Occigrip fit system dials in width for a precise, all-day fit. A snap-in liner pops out for quick washing and faster drying between days. What Our Gearhead(R) Experts Are Saying:"I wore this from a bluebird powder morning straight into a warm afternoon on the groomers without swapping gear. One turn of the rear dial opened the vents enough that I never had to pull the helmet off to cool down."
