For years I used a face shield because my eyes are sensitive to the
wind, and glasses were not enough protection. I attached a clear
lens, so at night or in the rain, all I had to do was take off my
sunglasses - no worries about changing glass lenses, and it was great
for bugs. The problem was that even though the set up came as if you
could snap on and snap off the face shield, it would not stay - so I
glued it in place. For about 4 years I used this set up and was happy
- except when it was hot out - no breeze on my face, it would be very
warm. As it turns out, last January I went to Australia, brought my
bike, but had a new very light helmet - and no face shield. My eyes
were ok, so I rode all of last year, including PBP, with out the
shield. I did miss it when early in the morning after the first
overnight ride on PBP, a bat flew into my face.
Here's where I got it from:
