The Anon Tracker 2.0 Goggles are sized for kids to create a comfortable fit that's helmet and eyeglasses compatible. They work with our MFI hoods, face masks, and neck warmers for seamless coverage from snow, wind, or sun. The cylindrical lens and flexible frame follow the natural curve of the face. Full-perimeter vents and our anti-fog treatment help maintain a clear, fog-free view come storm or sun.
