The Pas Normal Studios Womens Mechanism Thermal Long Sleeve Jersey is expertly crafted to maintain an aerodynamic fit, conforming seamlessly to your riding posture. The front and arms are made from Swiss Schoeller fabrics that are both wind- and water-repellent, ensuring top-notch protection against the elements. The back panel, on the other hand, features M.I.T.I SuperRoubaix fleece, which is exceptionally soft and breathable. Both fabric types are treated with DWR to enhance their moisture-resistant properties, keeping you dry in challenging conditions. The jersey also includes a heavy-duty YKK zipper and prominently displays the Pas Normal Studios logo on the chest and a reflective logo on the back for added visibility.
