Summer mountain bike rides are often tougher than a basic jersey. All-day outings on the trail require the use of a backpack, which frequently abrades jersey fabric, shortening the life span of what was once your favorite cycling piece. The Gore Bike Wear Women's Alp-X 2.0 Short-Sleeve Jersey , part of Gore's newest line of mountain bike performance wear for women, is built to last, in addition to being packable, durable, and versatile. The line has common ventilation features throughout so it will perform as well when used with matching pieces as it does individually. The Women's Alp-X 2.0 Jersey is a true off-road piece. The breathable, stretchy, fast-drying microfiber fabric has excellent thermoregulation qualities and is lightweight to boot. Mesh inserts are sewn on the sleeves, underarm, and paneling on the front of the jersey to allow for maximum ventilation. Mesh down the center of the back adds a cooling feature so you aren't doubling up when you're wearing a pack. For additional ventilation, a full length zipper with a semi-locking slider gives you the ability to unzip the jersey to exactly where you want it without the worry of your zipper coming undone. The zipper's underflap runs the entire length of the zipper, protecting your undergarments and shorts from abrasion by the zipper. Silicone prints on the shoulder makes the area where pack straps lay abrasion resistant so your jersey lasts longer, and keeps the straps from slipping as well. The Alp-X 2.0 jersey is sewn into a slim fit with contrasting flat-lock seams that eliminate chafing where seams commonly rub. Ample storage pockets on the back of the jersey make it easy to go packless when the occasion calls for it. Two compartment pockets and a pump pocket on the rear offer organized places for ride nutrition, spare tubes, and your hand pump. Two mesh side pockets add easy access to your camera or bars. Partially elastic gripper on the hem keeps the jersey in place. The Gore Bike Wear Women's Alp-X 2.0 Short-Sleeve Jersey comes in Citrus Green, Pool Blue, Thai Pink, Earth/black, and Black. It is available in sizes from X-Small to XX-Large.
