The Anon Helix Goggle was made for everyone who needs a set of goggles, not a fashion statement. The cylindrical polycarbonate lens blocks UV rays to protect your eyes, and is mirrored to reduce glare. Plus, the flat profile keeps the lens tucked into the frame, making it harder to scratch. The Full Perimeter Channel venting maintains a great air flow, so these puppies won't fog up when you're hiking laps in the park, or working up a sweat lapping the trees. Dual layer face foam keeps the Helix snug to your face, and they're fully helmet-compatible. They're goggles, plain and simple, and that's a good thing.
