Our most popular jersey, thanks to the warmth and excellent moisture management of our Warmer brushed-fleece fabric; the clean, purposeful design; and the large reflectivity panels on the chest and below the pockets on the back. Warmer fabric is a thickly brushed polyester fleece giving comfortable warmth with excellent moisture management. Reflective panels on front and back Gripper elastic at waist 3 rear pockets Easy-sliding YKK Vislon zipper. The third generation of the Puro Jersey, our most popular winter jersey, is better than ever.
