Funny you mention that, biking home last night enjoying the relative warmth (back into the 50s and certainly sunny after a frosty morning), I ran into a neighbor who was returning from a long athletic-style ride. I totally didn't recognize him through the neoprene thing covering basically his whole head but his face (apparently the blond hair is an important visual cue for me), and the shades covering a lot of his face too. I noticed he had neoprene booties as well.
