I've started to just go with it and get wet. Wool is awesome as I don't need to worry about getting cold, especially with a tight base layer and then wool sweater.

I sweat very easily so waterproof is not nice for me either. I rode in the rain this morning and to put on a shell type wind jacket (usually remove the arms to make i a vest and was fine there too. Rain slowly soaks through but I sweat through my layers anyhow. Wool would have been a better option in todays drizzle.

Of course, technical fabrics dry faster while at work than wool.
