For everything you put into your workout, you need gear that matches your output. Enter the Catalyst, a quarter-zip pullover that offers complete performance. Ideal as a middle or outer layer, the Catalyst is built with highly abrasion-resistant fabric featuring Enduro-Flex™ properties plus wicking and anti-odor finishes. Side vents help keep you comfortable in the heat of any moment. Little extras like a pen pocket on the left sleeve and a protective zipper garage only add to the Catalyst’s appeal. Perfection is in the details.
