The Castelli Breathe Attack Jersey is FAST! An aerodynamic construction is combined with lightweight, wicking, breathable fabrics making a great summer jersey for races or competitive rides. Anatomic panels that wrap around to back are combined with stretchy fabrics to create a cycling jersey that lies flat against a body whether you are in an all-out sprint or at the front chasing down a cyclist who is attempting to ride away from the peloton. The durable material is thin and exceptionally soft. Let in extra cooling air to keep from overheating by unzipping the easy to open full-length YKK Vislon zipper. Rear pockets are easy to access and provide enough room for cycling food.
