The updated FLY Racing Butane Jacket is a perfect all-season middleweight jacket. It features a Hydraguard waterproof/breathable membrane with advanced 600D material that is flexible, lightweight and durable. For cold weather riding, the Butane jacket offers a removable thermal liner. For hot weather riding, the Butane jacket offers an industry first Air Induction panel. This panel is located in the center of the chest and opens to expose a 3D mesh intake vent which allow a maximum amount of airflow for those hot days.
