MIPS takes crash protection to a new level, and you can get it on the Giro Sonnet MIPS women's helmet that could save your life without costing your life savings. MIPS multi-directional impact protection reduces rotational forces on the head during real-world impacts using an additional slip plane that mimics the way cerebrospinal fluid in the skull absorbs energy from collisions. With 25 Wind Tunnel™ vents, you'll be rolling in complete comfort, and the fit is easily customizable using the Roc Loc® 5 retention system with a dial tension adjuster and 3 points of vertical adjustment.
