The SPY05 is a new helmet baes on a new shell design with highly evolved deisgn from the SN2000 and WTT line. The shape of the front part, with its evident curve, makes it particularly comfortable, even when exposed to high velocity wind. The shape and position of the vents have been designed to optimise any turbulence.
