The Flexair Pro Fire Alpha Jacket is versatile enough for nearly any type of cold-weather riding.

Thanks to Polartec Alpha active insulation, the jacket's internal climate adjusts with changing conditions, eliminating the need to shed or add layers while riding. And, with a 10k/30k waterproof/breathability rating, it not only breathes exceptionally well but keeps you dry. Finally, because this is a mountain bike jacket, after all, Cordura panels have been incorporated to protect key wear zones, and a smart array of pockets ensure you can carry all your riding essentials.
