Giro Zone MIPS Helmet 2018
Wrap a soft tape measure around your head, keeping it level from front to back, just above your ears and eyebrows. Note the measurement and find your size below. The helmet should fit with a little room when the fit system is loosened, and sit low enough to protect your forehead without blocking your vision. Once you have the right size, dial in the fit with the adjustment system.
