Continuing Jacket Quest

Still looking for my perfect "commute" Jacket. Requirements are:

1. As casual/non-bikey as possible (without being baggy).
2. Windstopper style material (i.e. breathable, shower proof, fleecy on inside) as thin as possible.
3. Venting or more breathable material on pits/back/backs of arms (if possible – unlikely, seems to conflict with 1 above).

I've just had a look at Endura who seem to do about 20 different jackets. Any suggestions?

Sounds like you want the Gore Bike Wear Cosmo WS Softshell. Designed for your brief above!

Wow. That looks close!
