A staple for all San Francisco cyclists. Good for cold morning rollouts, bridge crossings, bomber descents, evening excursions, lunch runs, beer runs, doughnut missions, escaping the city, and wind. This vest is made from super lightweight and compactable ripstop fabric with mesh fabric on the back and sides. The ripstop fabric offers great wind protection along with water resistance while the mesh back and sides provide ventilation. Three rear pockets add storage space for extra gloves in the winter, and the dual direction zipper allows you to fine tune your airflow. Bonus: reflective binding at the top of the pockets for dawn patrol raids (the vest is also pretty bright on its own). Designed in San Francisco and hand-crafted in southern California.
