You will never feel incapable of performing on the mountain with the DX goggles by Dragon. By design these goggles are meant to accommodate every possible contingency. Whether it is a nasty fall, expect a durable polyurethane frame to stand the ultimate crash test. And no matter how intense the glare may be that day, the DX will provide you with 100 percent UV protection. Couple that with superior comfort provided by micro fleece lining and a dual layer of face foam and you got yourself an incredibly long lasting and functional pair of goggles.
