The Giro Jackson MIPS Helmet is a snow helmet for mountainous adventures. The in-mold construction and Passive Aggressive Venting System creates a modern helmet that focuses on style and is backed up with performance. The auto-vent technology regulates temperature and manages airflow, so the noggin is comfortable whether headed up the mountain or down it. It's ultralight to prevent a bobblehead situation and the In Form 2 Fit system allows for a dialed in, custom fit. This Mips equipped helmet protects in angled impacts, because you never know which way a fall may land.

HEAD CIRCUMFERENCE — Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide.
NOTE: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you have the right size, you can adjust the fit.
