The Mechanism Long Sleeve Jersey works well as a layering piece or on its own, throughout the year. With the perfect balance of style and function, the Mechanism Long Sleeve Jersey embodies Pas Normal Studios' commitment to exceptional technical apparel. Thanks to its soft fleece-backed fabric, this jersey is ideal for intense training and racing. Whether it's a chilly morning or late afternoon, the Mechanism Long Sleeve can be used as a standalone outer layer, or paired with a thicker base layer and a gilet or jacket for colder temperatures.
