【NEW】ARS-3 SHIELD "Photochromic"


 "Photochromic" is newly added to the ARS-3 Shield lineups.

 ARS-3 SHIELD (ARS-3), an optional shield for "AERO-R1", originally supplied exclusive to professional riders prioritized on practicability at actual games*1, which responded to the pro-riders' demands of light weight and color shields. However, with the strong demand of many users who find ARS-3, we realized commercialization。

"Clear Photochromic *2" to be added this time has a visible light transmittance of 88% at the lightest state, and at the darkest state it is 28%. With a single shield, it covers wide range of color state conditions. UV transmittance ratio is under 0.1%.

<NOTE on Photochromic Shield>

Photochromic lens is induced by ultraviolet (UV) irradiation. As so when it is under the UV light, it darkens, and when the UV light is blocked, it will not darkens.

The color shifting speed and color density may vary according to the usage environment.

Photochromic lens will degrade with age, causing the color shifting property gets desensitized.

Do not store in a place where it is exposed to direct sunlight, inside a car under the scorching sun, or in a drying room etc. Also avoid high temperature and high humidity place.
