EXTRA SHIELD is one of the original brands of YAMASHIRO (Tokyo, Japan), which is also well-known as a manufacturer in the Japanese market.

EXTRA SHIELD has been developed by the optical background to reduce defuse-reflection and view-gain that causes eye-stress for riders.

Now you can add-on "Grade-1 Optical Performance" to your helmet which is giving a great view that you have never experienced.

EXTRA SHIELD is made from the genuine base visors of Arai & Shoei Helmets to guarantee the perfect fitment on the helmet.

 This is a crucial factor for you to upgrade your premium helmet with properly developed items rather than you downgrade your premium helmet by installing copied visor which is proven to affects your view sight.

To provide the best view sight for all riders, R&D is always our entry point every time we release the new visors.

EXTRA SHIELD is not a simple mirror-coated visor.
Our promise is to provide you the best optical performance throughout product development by a specialist in the optical field.
