i wear wool and for longer tours take two jerseys, three pairs cycling shorts. shorts washed every night if possible, dry night and next day on rack with the third set of fresh dry shorts in bag. jerseys washed every few days, experiences like NoGa biker with the wool. I wore ONE wool jersey five days straight once on a blitz tour as i was packing light. didn't smell too bad after 500 miles of desert and high mountain passes.
