These ski goggles feature a magnetic cylindrical lens system for quick lens changes and secure retention on the slopes. The dark blue REVO lens helps reduce glare and eye strain while maintaining clear visibility in snowy conditions. A dual-vent anti-fog design and triple-layer foam improve airflow, warmth, and all-day comfort. The OTG frame fits most glasses up to 4.7 x 2.3", and the adjustable strap is designed to work with helmets. Built with a TPU frame, they are suited for skiing, skating, and snowboarding.
