Prepare for another best day ever spent on the mountain while wearing the Giro Jackson MIPS Helmet. Designed with MIPS technology, the helmet absorbs impact force and redirects energy through the MIPS two-part system. The Hardshell exterior and in-mold foam interior work together to disperse and minimize the shock through the impact. The Passive-Aggressive venting system works to keep the interior of the helmet cool without being too cold. Escape vents allow for heat to move out of the helmet while in motion and at rest. On especially warm spring days, the XT2 padding resists odor to help maintain a fresh, like new feel and smell.
