It never gets easier; you just go faster. CASTELLI have incorporated a lot of their pro racing technology into this all-around performance jersey. The base fabric is a textured 100% polyester that provides excellent wicking to keep you dry in a wide range of conditions. CASTELLI have wrapped their Air Mesh fabric around the shoulders and down into the sleeves and side panels to give extra stretch so the jersey doesn't constrict or make you look like you should bought a size larger.
