sweatpants = warm-up pants?
I like a road jersey for the full length zipper - gives nice control over body temp. I do stick things in the pockets - a snack, Clif Shots, cell phone (not that I want to talk but I'm basically always "on call"), etc. But I guess I could just stuff that stuff in the pockets of the shorts I wear over my road shorts.
Surprisingly, I found there was a BIG difference in fabric between a nice Pearl Izumi jersey and Performance's cheapest jersey.
