I’ve been using a plastic visor that Duncan Cleland scored as a freebie on one of the mass rides.

It’s perfect for HPVs because it is very big and can be tilted forward on your helmet.
Works great on the lowracer with the reclined seat.
I scanned the outline and indicated where the couple of velcro patches should go in red.
The diagonal black lines are where the plastic needs to be “scored” to enable it to fold.
The plastic material is quite thin (about 1mm) and similar to a plastic presentation folder.
