Not every training ride has weather that includes bluebird skies and 70 degree temperatures, with a slight tail wind in both directions. Some days the headwind seems to come from every direction, pushing through every fiber of your jersey, sucking away the last of your self-confidence and taking with it any warmth left in your body as you ascend a windy mountain pass. Although the weather cannot be controlled, putting on the Gore Bike Wear Women's Oxygen SO Jersey can lessen the blow of harsh winds, keeping your sense of indomitability intact and your body protected from the elements. Sitting close to the top of Gore Bike Wear's line of women's road jerseys, the Women's Oxygen SO Jersey is situated between the Xenon and Power. The Oxygen SO uses Gore signature WindStopper Soft Shell on the front. But it doesn't stop there. Well-placed wind-proofing on the shoulders and kidney area protect places on the body commonly affected by wind chill on descents or windy days. This, combined with a cozy nylon-elastane jersey fabric elsewhere, makes this jersey a perfect option for cool spring days and dry conditions. Windproof material isn't the only thing that makes the Oxygen XO Jersey an ideal top for cool-weather rides. Contrast flat-lock seams reduce chafing and skin irritation caused by protruding seams . An underflap runs the length of the zipper to keep it from catching on your undergarments and irritating your skin as you ride. Zip ports on the top and bottom protect your neck and favorite shorts from being abraded by the zipper. A partially elastic gripper on the hem keeps the jersey in place, even when the three-compartment rear pockets are weighed down with nutrition bars and tools on long rides. In addition to the three standard pockets, a zippered pocket adds secure storage for keys and credit cards. Reflective piping on the back sleeves and logos on the front and back keep you visible during early evening and morning rides. The Gore Bike Wear Women's Oxygen SO Jersey comes in Black/white, Black/pool blue, and Black/fuchsia. It is available in X-Small to XX-Large.
