Riding cloths. Two white synthetic shirts (from when I used to play ultimate frisbee a lot more). A pair of riding shorts, they have padded commission shorts inside. Two pair hiking socks (which have now been replaced by black biking socks). One pair long liner socks, for tucking in pants or preventing blisters. One pair biking shoes, with SPD cleats. Not much to say, they get stinky and I wash them. I didn't bring lots of extra clothes, because the weight and discs really adds up, so I try to wash every two or three days, though I can go for a while with out if need be.
