Protects from 99% of the sun's damaging UVA and UVB rays.

Photochromic performance is influenced by temperature, UV exposure and riding posture. PLEASE NOTE!
Photochromic shields darken faster than they lighten and the process is influenced by temperature. On a sunny day, they will reach maximum darkness in approximately 20 seconds. Complete activation occurs in 120 seconds.
