Our Classic Messenger Bag. Designed in San Francisco over 30 years ago, enhanced with modern upgrades. The imroved shoulder strap features a curved airmesh strap pad for comfort, durable webbing, and Timbuk2's Double-Loop CAM buckle for quick adjustment and to eliminate dangling straps. SR buckles are partially concealed behind the messenger flap for a refined but secure closure. Inside, the waterproof TPU liner and corner wings keep water out, and the internal water bottle pocket keeps water in. Distributed internal pockets and organization balance the weight of your carry. Removable crossbody strap add stabilization on sizes small and up. Exterior water-resistant finish for protection in light rain.
