Looking for a cycling jacket for Fall/Spring I am looking for a cycling jacket for fall/spring.  Depending on how well it works I may use it through (part of) winter as well.  

I did a bit of shopping last night and purchased this MEC SuperMicroft Cycling Jacket.  



I brought the jacket home and began having second thoughts.  I am thinking about returning it and continuing my search.  Here are my requirements:


Cuts the wind
Will not become like sauna inside making me soaking wet
Has good road visibility
It doesn't have to be extremely waterproof but being able to fend of a light shower would be nice


My main concern with this jacket is the breathability.  It has pretty big armpit zips.  It is made out of "Super Microft™ microfibre polyester, which is soft and quiet like cotton but tightly woven and treated with durable water repellency (DWR) to shed water".  It feels like the fabric will cut through the wind well but might leave me very wet inside.  The jacket does not have any kind of back vent which may be problematic.  

I am riding in Ottawa, Ontario, Canada.  It has been pretty wet here lately.  I haven't riddin in the rain too frequently but the roads are always wet (thank you fenders).  The temperature I want to use this coat in would be about +7C to -2C and maybe colder if I can layer correctly.  

Open questions:


What do you use when cycling in cool weather to keep the wind from chilling you and keeping the moisture away from your body?
Does anyone have any views on this jacket?  Would your recommend something else?
I also live in Ottawa, and the last week I've been wearing this MEC Cycling Jersey, along with another regular jersey and a cotton white T undershirt underneath.  This has been sufficiently warm for my 20 minute commute.  My arms get a bit cold, because they only have 1 layer, so I think I may pick up some arm warmers if it gets too much cooler, but I don't think it's really necessary. Other than that I don't have too many problems keeping myself warm.  I find that using lots of layers really helps to cut the wind, without compromising breath-ability.  As far as other clothing goes I have the Roubaix Tights which are worth every penny.  Have kept my legs toasty warm, while not making me sweaty, even in the cold (-1 degree C) we had this morning. Like the jacket that @geoffc mentioned, they have different material on the front and back.  The front blocks out the wind, and the back lets your legs breath and lets some of the heat out. Only problem I have is keeping my hands warm.
