Strong Impact Resistance: The spherical protective glasses use a flexible TPU frame and shatterproof PC lenses to protect the eyes from impacts while skiing. Even when hit during impact, the lens blocks the shock from the front, while the frame and thick foam cushion the blow. UV 400 Protection and Anti-Fog: The ski goggles are used for sun protection while skiing and also as protection against snow glare. Made from Italian anti-fog lenses with two layers. Since the sun reflects off the snow at high altitudes, the snow goggles protect the eyes from strong glare. OTG Design and Comfort Foam: The OTG (Over The Glasses) design allows you to wear the goggles over prescription glasses. Even if you are nearsighted, you can still enjoy the sport. At the same time, the thick foam ensures a comfortable and snug fit, providing a better skiing experience. Adjustable Head Strap and Helmet Compatibility: The high-density head strap with excellent elasticity consists of two straps for better adjustment of the strap length, ensuring great helmet compatibility for all helmets. Optimal Ventilation System: The snowboard goggles are designed to reduce fogging and improve airflow over the inside of the lens. The ski goggles ensure consistent airflow that quickly and effectively removes moisture while skiing.
