I don't commute, but i do ride in the winter on occasion of dry roads. I have a pair of the tights mentioned by nanci that are the wind proof/almost water proof tight. they remind me of something like a rubber material, but they work like a charm., and the backs of these tights are regular material so they vent okay. i also have a jacket that i bought on clearance from a sports shop, that is made from the same material as the front of the perfomance tights but the inside reminds me of long john type material. they said it was more for x-country skiing activity but it works perfect. i usually get by with a tundra jersey from performance or a hooded winter jersey from a LBS and this jacket. granted i ride in high 30degree range maybe 40's with these and do fine. i defintaly use the ear band wrap-a-mabobby thing if i don't wear the hooded jersey. gloves are going to be my next investment, using x-country ones now but not enough padding in those, sad to say it's august and i'm looking at the winter catalogs already. but i've gotten some ideas already from this thread, so thought i would share mine..
