Even the most dedicated cyclist will find himself off the bike from time to time. For these rare occasions, Castelli has created the Advantage Short Sleeve T Shirt. Made from a 6040 cotton and polyester blend, the Advantage T Shirt features contrasting neck tape and screen printed logos. Since we don't only sweat in the saddle, the Advantage is made with a treated cotton that helps with moisture management. Sizing is pretty standard as far as T shirts are concerned. For reference, someone who is six feet tall and weighs 175lbs will fit a Large shirt very well.
