I haven't bought anything special for my winter ventures, i chuck on the golf wet weather stuff (its only shower proof not expensive waterproof) and away i go. As someone else has said it is more dry than wet on average anyway. I use the winter just to keep me going, a little often half hour here and there. The golf wet weather gear wont go near a golf course for a few months anyway, most courses have too many restrictions or are like the Somme in winter so its a waste of time.
