Like a hybrid between a jersey and a jacket, the Castelli Sfida 2 Long-Sleeve Full-Zip Jersey is one of our favorite pieces of riding apparel for chilly fall rides. Made with Nido d'Ape 3D Thermal fabric, the Sfida 2 Jersey gives us warmth and a little protection from m the wind while being surprisingly breathable. An extra-high Zen collar helps to protect our neck from the cold, and a full-length YKK Vislon zipper gives us the option of customizing our warmth. A triple rear pocket design allows us to take along our ride essentials, while reflective details help to keep us seen in low-light conditions.
