Fox Flexair Pro Women Jersey Technical, high-performance mountain bike jersey. The Flexair Pro Jersey is injected with no-compromise features that bring the best technology to a free-flowing, durable mountain bike jersey. Maximum cooling comes from the Polartec Delta panel on the front, while abrasion resistance is handled by Dyneema at the shoulders and its carvico sleeves. Its tailored fit allows for plenty of unrestricted movement, leaving you free to confidently tussle with the rough stuff in this high-performance jersey. Polartec Delta front panel for maximum cooling. Dyneema shoulders increase abrasion resistance and reduce weight. Carvico sleeves add abrasion resistance and venting. Bonded front hem, sleeve, and neck openings reduce chafing. Body-mapped laser cut perforations increase cooling. Tailored fit sits close to body without being restrictive.
