The Royal enters the ski mask collection from Bollé. This model offers a wide field of vision thanks to its minimalist frame design and Carbo Glas anti-scratch treated spherical lens. The double lens creates a thermal barrier between the cold outside and the warm air inside. Combined with the Flow-Tech ventilation system and P80+ anti-fog treatment, everything contributes to preventing fogging on the screen's inner surface. Compatible with the wearing of a ski helmet, the Bollé Royal is very comfortable to wear with its double density foam that prevents unpleasant draughts. This description is an automatic translation.
