My only concern with that jacket in socal is that it may make you too hot.

I live in the Seattle area, and only if it's under about 45F and raining do I put mine on, over a short sleeved jersey, with full finger gloves. Otherwise I overheat even with the pit zips wide open and the chest zipper open enough to get me wet. I should say I do run pretty hot on the bike though.

I love my jacket though. When it's 35-40F and raining (which it pretty much is every morning in the winter here) it is perfect. The price is right, it's put together well, pretty high tech, and comfortable.

(edit: No zipper issues here. probably about 1000 miles on the jacket.)
