Rock your favorite windproof jersey with new styling to celebrate Gore Bike Wear's 30th anniversary in cycling. The men's Short Sleeve 30th Anniversary Oxygen WS SO Jersey features special edition graphics to celebrate Gore Bike Wear's time in the industry. The Oxygen WS SO uses Gore's signature WindStopper softshell fabric on the front to block out chilly wind gusts with strategically placed windproofing on the shoulders and kidney areas for additional protection. Combining Windstopper with a cozy nylonelastane fabric means the top is perfect for cool spring days and dry desert conditions. contrast flatlock seams further the Oxygen's appeal by reducing chafing and skin irritation. An under flap runs the length of the zipper to prevent catching on undergarments or skin, and a partially elastic gripper on the hem keeps the Oxygen in place. Three rear pockets provide ample space for cookies and other ride necessities, while an additional zippered pocket adds secure storage for keys or credit cards. Reflective piping on the sleeves and logos at the front and back increase visibility during the low light conditions of early evening and morning rides.
