I commute all year round and I decided to try switching from wearing full-on waterproof clothes to the quickest drying things I could find.
So far, very pleased with my Giordana Body Clone jacket (http://www.chainreactioncycles.com/Mode ... elID=46776
) which is a lot warmer than I expected given it's so thin and weighs next to nothing and can resist the lightest showers, and never takes more than 10 mins to dry. Most importantly for me, it's very breathable, so never feels clammy.
I bought some Teva churn shoes, which are not particularly warm, but great for three seasons in that they also dry very quickly. I still wear overshoes over them on the wetter days though. I've been through a few different makes of overshoes - The Pro ones I had were good waterproof and very warm, but the thicker neoprene was less flexible, which meant they seemed to get tatty quite quickly (still lasted me a couple of years) The Primal Crankenstein ones look excellent, but were terrible, with the inflexible hard rubber bottoms making them very hard to take on and off and the seams leaking from the very first ride. At the moment I have some Giordana ones (these I think: http://www.chainreactioncycles.com/Mode ... elID=39173
) which have so far been good - fully waterproof and very flexible and easy to get on, though I haven't tried them in winter yet, so I'm not sure how warm they are and the back of them can rub on your calf a little, but that seems to be the case with quite a lot.
In terms of gloves, apart from in winter I tend to wear thinner ones again, excepting they won't keep my hands dry in prolonged rain, but that they'll always be dry in time for the next journey.
I hope some of that is of use!
