Bontrager's RXL Jersey is a serious top for serious and recreational riders alike. It uses dynamically breathable Temptech fabric and strategically placed Contura side panels and shoulders for a moisture-transferring, quick-drying jersey that keeps you comfy on every ride. The cut is fitted with textured silicone grippers at the waist and cuffs for a superior fit. There are 4 back pockets: 3 standard ones and a water resistant MP3 pocket with a wire portal and cycling specific cord management. And you've got a full length, semi-locking zipper.
