Bolle Sierra ski goggles

Bollé Sierra Ski Goggles – Uncompromising Vision & Comfort on the Slopes

Experience the mountain in its full glory with the Bollé Sierra ski goggles, engineered for skiers and snowboarders who demand clarity, comfort, and protection. Designed to provide an exceptional field of view and all-day performance, the Sierra is your essential partner for carving down groomers and exploring fresh powder. Forget about distractions like fog and glare; these goggles are built to ensure your focus remains squarely on the line ahead.

The Bollé Sierra combines classic style with modern technology to deliver an unparalleled visual experience. At its core is a high-quality double cylindrical lens, which not only provides a wide, panoramic view of your surroundings but also creates a crucial thermal barrier. This dual-pane design significantly reduces the chance of fogging by separating the cold outside air from the warm air inside the goggle, ensuring your vision remains crystal clear from the first lift to the last run.

Stay Fog-Free in All Conditions
Never let fog obstruct your view again. The Sierra features Bollé´s advanced Flow-Tech® ventilation system, an engineered venting design that promotes directional airflow across the inner surface of the lens. These vents reduce moisture buildup while preventing clogging from snow and ice. This active ventilation is complemented by a premium anti-fog treatment layered on the inner lens, offering a robust, dual-action defense against condensation, no matter how hard you´re working or what the weather throws at you.

Durable, Protected, and Adaptable Vision
Built for the rigors of the mountain, the outer lens is fortified with a protective anti-scratch treatment, safeguarding your goggles against accidental drops and encounters with branches, ensuring long-lasting optical purity. Your eye safety is paramount, which is why the Sierra provides 100% UVA/UVB protection, shielding your eyes from the harmful effects of the sun´s radiation, especially at high altitudes. For ultimate versatility, the Sierra is also available with advanced photochromic lenses that automatically adapt to changing light, darkening in bright sun and lightening in overcast conditions, so you always have the perfect tint.

Designed for Universal Comfort and Compatibility
The Bollé Sierra is thoughtfully designed for a universal, standard fit that suits most adult face shapes. As a unisex model, it is an excellent choice for both men and women. Acknowledging that perfect vision is key, these goggles are fully compatible with prescription glasses. The strategically designed frame features subtle cut-outs in the side foam to accommodate glasses arms comfortably, making it a true Over-The-Glasses (OTG) solution without compromising on fit or performance. This model, with its Category 3 lens, is perfectly optimized for sunny and bright light conditions, cutting glare and enhancing detail.
