I found a box of "Disposable Nitrile Gloves" laying in the road. - (food service gloves)
Tried one on ... gigantic.
Hmmmm ... "X-LARGE"!

Fit right over my comfy felt gloves.
Blocked all wind and wet ... and gives a nice rubbery grip.

Just have to find matching "Disposable Nitrile Mittens" for my shoes ...
