Sorry, should have clarified about what I was already wearing.
Fingerless gloves, regular shoes, padded shorts but I am wearing some long running shorts over them to protect my decency and Dri-Fit shirt.
What water proof jacket are you using?
Looks like some fingered gloves might be in my future as well as another pair of shoes I can wear once I get to work if my feet do get wet from rain while riding.
