Engineered to perform on the piste, the Sin Valley Ski Goggles offer top-tech boarders and skiers alike. Starting from the inside, 3-layer overlapping, hypo-allergenic foam ensures ultimate comfort and a secure fit. On the outside two lenses are included and are changed by a magnetic changing system, one orange oil CAT 3 and a pink CAT 1. The double cylindrical construction of both lenses ensures optimum vision whilst the ventilation system and anti-fog coating prevent misting. FInished with an adjustable and anti-slip strap for the perfect, personalised fit, the Sin Valley Goggles are a cut above the rest.
