Offering exceptional wind protection, the Q36.5 Air Vest uses advanced, lightweight material to insulate while remaining super packable, meaning you won’t even notice it in your back pocket during warmer moments of the ride. Designed for 4-season effectiveness, the Air Vest is perfect for everything from cold, windy winter rides to summer rides high in the mountains. Its body mapped cut ensures it will sit close to the torso and not flap in the wind.
