I am rather partial to my MEC jackets. Pit zips are a must.

Asking this sort of question is a bit like the CF/Ti/steel, Brooks/Others, Shimano/Campy, etc etc etc threads... there is no definitive answer.

Plus, you might help us out by telling us what you use already, what you consider its weaknesses, what amount of money you are prepared to spend, how much volume you expect it will take when not being worn, and how hot or cold you ride and how much you sweat...
