I have a wool one from Woolrich that they don't make anymore, which is great on the bike.

This one is kinda like it: http://woolrich.com/CGI-BIN/LANSAWEB...948056+PRD+ENG Not bad for $39.

This one is even cheaper, a lighter weight boiled wool and no pockets. Not bad for $31. http://woolrich.com/CGI-BIN/LANSAWEB...948056+PRD+ENG
