Tips

Photochromic lenses respond to UV light, so on cold but sunny days the tint will be darker. To preserve the anti-fog coating, rinse with fresh water and dry with a soft cloth. The side shields are ideal for exposed ridges, but you may want to remove them when climbing to improve peripheral awareness.
