  • Saving you £80

Gore Wear Women's Skyline Cycling JerseyA bold print is the first thing to catch the eye with the Women's Skyline Cycling Jersey from Gore Wear. But not just good looking it performs brilliantly, the technical fabrics and slim fit offering outstanding cycling comfort. To keep you comfortable on warmer summer days, the Women's Skyline Cycling Jersey is made from a quick-wicking fabric. This not only draws moisture off the skin to keep you dry and comfortable, but it's also quick to dry, preventing a soggy feeling when you stop for your mid-ride cafe stop. If you do feel too warm, those steep hills soon build up heat, then a full-length front zip makes it easy to boost cooling airflow. Thanks to its slim fit and road-specific tailoring, featuring longer than standard sleeves and a drop tail, the Women's Skyline Jersey aids your smooth progress through the air. And when you drop into a lower, more aero cycling position, an elastic gripper keeps the jersey snugly in place. From multi-tool to gels to emergency jacket, three back pockets provide space for your cycling essentials. A zipped pocket also keeps keys and cash safe. And for long summer rides that stretch into the fading light of evening, reflective details will make you easier to spot on the road home.Features:Materials: 100% PolyesterLengthened sleeves and dropped tail for modern cycling fitFull-length zip2-gusseted back pocketsSecure zip pocket on the rear for keys or valuablesGrippy insert at the back hemReflective detailsForm-fit - closest Gore fit, designed to be worn tight to the bodyBuy Gore Wear Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.
