Skiing in prescription glasses usually means picking a goggle that fits over them and hoping the helmet cooperates. Index 2. 0's extra interior volume and temple cutouts make room for glasses without pressure, and the Sario MIPS Helmet's vertical tuning adjusts to meet that larger profile instead of leaving a gap at the brow. What Our Gearhead(R) Experts Are Saying:"I used to lose the fight against fog and pressure wearing glasses under a goggle. Locking Index 2. 0 into the Sario MIPS's retainer against the tuned brim ended that, run after run."
