When the run gets fast and the laps stack up, the Revi Challenger Snow Helmet stays light on the head while protecting it. This ski and snowboard helmet pairs a hybrid dual shell of ABS for durability and polycarbonate for weight distribution with zoned EPS foam. The ESA Shock Absorption System is integrated with the foam to disperse energy and reduce force transfer. What Our Gearhead(R) Experts Are Saying:"The goggle retention clip is why my goggles stay put on fast, bumpy runs, so I stop adjusting them between laps. The audio-compatible ear pads hold a drop-in speaker in place, and it stays there when I'm riding hard."
