The United States Constitution Womens Bicycle Jersey is made from 100% Polyester DrySport tm wicking fabric to effectively move moisture away from your skin to keep you cool and collected. Since our jerseys are made to look as good as they feel we hide the 14 zipper to keep the pattern clean and elegant. And speaking of a clean and elegant pattern, we use a heat sublimation process to print our 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; no sense going to all this trouble and then having it fit like some crummy t-shirt! 100% DrySport Polyester Wicking Fabric 14 Hidden Zipper High-tech Heat Sublimation Printing Elastic Waist and Cuffs Cycling Cut, Three Back Pockets
