DeMarchi jerseys were available for awhile at Sierra Trading Post for a good price. I got the French one. They are a tad itchy, and I like wearing them over tee-shirt style base layer, maybe in a smooth itchless merino.
These would be nice for credit card touring, because with the wool, they don't look so cycling specific, and you can wear them as a shirt with pants après ride, which means there is one less shirt to pack. Also, the wool is comfortable over a wide range of temperatures (to about 75 degrees), remains comfortable when damp, and will remain odor-free over several days.
Am I right about this Duppie?
