is the reason to waer a jersey is cause they are colorfull and make it so people see you better? reason i ask is cause im starting to ride my bike to do erins and thats in the city type stuff.. also found some really cool pink floyd ones... im not one of those people that ride 100miles a weekend "not yet" so im wondering is there really any reason for me to get one? also are they supposed to be tight or kinda loose? or just like a t shirt? oh and i dont do drugs or anything just like the music but one could say a PF jersey may in someway condon using lsd or smoking pot...
