Kate Middleton, the fiancée of Prince William of Wales, wears Bollé Boost ski goggles during a 2008 vacation in Switzerland. The full name of the model is Boost OTG Vermillon 20421: OTG stands for Over The Glasses meaning they fit over (prescription) glasses. The lens color is Vermillon and the frame is Black Basics. The Boost is available in other color and lens combinations and the current model is slightly different from the 2008 model, and features the new Bollé logo on the band and frame. The Boost is quite small, and recommended for children (age 6 and up) or small adult face sizes.
