2nd set of goggles
This is a second set of the goggles for me. They have improved the design with a semi-hemispherical lens instead of the flat one. They have designed off the detachable battery door so it does not fall off like the other (Smith was really nice and sent me a replacement FOC last time). The new one only has a single battery. This could be enough because I got the prescription lenses. The old one was using my glasses.
