The Treviso Defender Goggle is built for skiers and snowboarders who want clear vision, a comfortable fit, and easy performance in changing mountain conditions. A magnetic lens-to-frame connection makes lens changes quick and simple, so you can adapt when the weather shifts from bright sun to low light. Two spherical mirrored double lenses are included: one for bright conditions and one for low-light days. The spherical lens shape helps provide a wide field of vision, while the double-lens construction adds protection and clarity on the mountain. A silicone-backed strap helps keep the goggles secure on your helmet for a stable, comfortable fit. For added convenience, the goggle includes a nylon lens-cleaning carry bag and a zippered hard shell case to help protect your gear when not in use. The RS removable strap design also allows for optional strap customization.
