The 1948 USA Olympics Cycling Jersey is made from 100% Polyester DrySport wicking fabric to effectively move moisture away from your skin to keep you cool and collected. Since World Jerseys' jerseys are made to look as good as they feel, they hide the 15″ zipper to keep the pattern clean and elegant. And speaking of a clean and elegant pattern, World Jerseys uses a heat sublimation process to print their jerseys, which bonds the bright colors to the feel-good fabric. That just means it stays looking bright wash after wash. Elastic waist and cuffs keep the jersey in place so it wears the way you move. Three large rear pockets keep your stuff out of your way so you can keep just dig in and enjoy the ride. By the way, the cut is designed for cycling; so please look at the size chart.
