Errrrrr....Waterproof gloves or overgloves?
I've been through torrential rain loads and loads of times on my ST and as long as I've been wearing the right gear I've never got the tiniest bit wet. Pop some overgloves under the seat.
Now doing trackdays in the pouring rain wearing just leathers and summer gloves is a different matter....I had purple hands for days where the black dye ran out of my summer gloves
