As a go-to, year-round helmet that prioritizes fit, performance, and protection, Oakley's MOD3 Helmet is a winter sports favorite for all the right reasons. To get the exact fit you're looking for when you're slaying the slopes, the BOA Fit System dials you in with a 100% adjustable, full coverage fit that gets locked in with the magnetic FIDLOCK buckle that quickly secures and fastens with ease. On long days hitting the gnar, the versatile ventilation allows hot air to escape from the top to cool you down or can be closed to get warm again.
