Giro Ratio MIPS Helmet

Stay protected while hitting the slopes with the Giro Ratio MIPS Helmet. This ski and snowboard helmet features a dial-fit system that adjusts to your head shape with a discrete micro-adjustment dial on the back of the helmet so it stays in place and you don't have to readjust your helmet constantly throughout the day. With adjustable vents you can open and close them quickly with the switch of a dial and a hardshell construction, you'll stay safe and protected where it matters most.
