Ice particles, high reflections of the sun from the snow, wind, and small debris are just scratching the surface as to why goggles are important. You'll have a much more enjoyable experience with goggles than without, and you'll thank us for the recommendation (and yourself for choosing to following said recommendation) after that perfect session. There's a wide variety of goggles available, from the lense shape to the ventilation to lense color. Every aspect alters your skiing ride, and you should take into consideration what you're looking for as a rider.
Still not sure? Give the shop a call. We'll be happy to help you find the perfect goggles for you!
