If the product was originally designed for skiers and snowboarders, I quickly diverted and used his protective characteristics for water sports. The outer polycarbonate lenses impact resistant protect the eyes from splashes of water and dust. The surface treatment and the orange yellow color of the glass (UV protection indicated 400) considerably soften the reflection of the water surface even in bright sunlight. Finally fast navigation, I did not feel any air inside power, nor fogging. These glasses, provided with a wide elastic strap, are pressed against the face and although still very comfortable to wear. Finally a good surprise, this ski mask comes with a drawstring bag and a two year warranty.
