Frequently Asked Questions
The FUTR LenZ™ is a proprietary technology engineered to deliver maximum optical clarity, allowing for fast, precise performance. It minimizes distortion so you can read the terrain perfectly whether you're freeriding, racing DH, or riding enduro.
SCREENZ™ 360 is a full-airflow ventilation system designed to actively prevent fogging. It ensures continuous air circulation throughout the goggle, maintaining a clear view even during extreme physical exertion when body heat and sweat are at their peak.
Absolutely. The goggles are designed for elite riding across multiple disciplines. Whether you're tackling a downhill (DH) race course, navigating an enduro stage, or enjoying a freeride session, the clarity and fog prevention work to keep up with the demands of each style.
While designed for optimal integration with modern full-face and open-face mountain bike helmets, we have engineered the frame and strap system to provide a universal, secure fit across a wide range of helmet brands and sizes to prevent goggle gap.
Eco-Performance is our core philosophy. It means you don't have to choose between top-tier athletic performance and environmental responsibility. Our products are designed to use more sustainable materials and methods without ever compromising the critical performance a serious rider needs.
While both share our core FUTR LenZ™ and SCREENZ™ 360 technologies, they are purpose-built for their respective environments. SNOW goggles are optimized for cold weather, reflective light, and glacier use, while DIRT goggles prioritize maximum ventilation and tear-off compatibility for mud and dirt. We recommend using each for its designed sport.
