There are a number of such things made for hikers. Try REI. Guess the problem would be keeping it away from your face while you ride with the ever-present effective headwind. OR makes one with metal rings that might help. The other problem would be seeing. They really obscure your vision. Maybe it needs to be integrated with cycling glasses. How about a plastic bubble face shield like motorcyclist wear? Probably too hot and would fog. Gee Nanci, you come up with hard problems.
