WeePro® PHA (Photochromic, Heat-resistant, Anti-fog) Insert

Sun-glare is a headache for most motorcyclists. You even can’t open the eyes when you are riding under sunny or cloudy days.

WeePro® PHA Insert can change from clear to different dark levels rapidly under different level of UV ray. The photochromic visor is clear at night. During the day, the PHA insert will be slightly darken and becomes light grey. And it will self-tint to a decent level of dark on a sunny day.

With an UV (Ultraviolet) and IR (Infrared) filtering property, WeePro® PHA Insert can cut 99.9% UV light and more than 80% IR light, which can prevent you from burning by strong sunlight during long riding.
