The Shinobi is our aggressive premium model with a solid lens mount for high-speed applications. Never let poor vision hold you back again. The Shinobi has the same high-quality, 2.2 mm thick, machine-ground toric lenses as the Ronin and is equipped with extremely stable and simple lens changing technology. To change the lenses, simply push back the two buttons on the temples and press in the middle of the nose bridge ? and the lenses can be removed or inserted. The Shinobi offers excellent integration with all our helmets, and the temples are designed to be as unobtrusive as possible to maximize comfort. A hard case, a microfiber bag and three different nose pieces are also included to guarantee an optimal fit.
