The Capo Women's Siena Long Sleeve Jersey is designed to meet the needs of almost any rider for almost any ride this fall and winter season, with simple but bold style and a host of advanced fabrics to protect you in cooler weather conditions. The Siena jersey falls into Capo's Corsa family, aimed to provide excellent fit and true Italian style and craftsmanship without sacrificing functionality. To that end, the Siena employs some great fabrics. The jersey is constructed from Capo's Thermo Roubaix fabric, a hollow core polyester material. Thermo Roubaix is engineered to allow great breathability, so as to not encourage excessive perspiration, yet it also insulates extremely well to protect from the cold. Helping it in this regard is its high degree of water and wind protection. While not ready to protect you from a downpour, the jersey will easily fend of mist or a light precipitation. The full length zipper up front helps to ventilate, while in back there are three cargo pockets to carry your essentials. The Capo Women's Siena Long Sleeve Jersey is available in four sizes, from Small to X Large, and in three colors: Cyan, Red, and Royal.
