Classic Messenger - Medium Gunmetal. Our Classic Messenger Bag. Designed in San Francisco over 25 years ago. The shoulder strap features a curved airmesh strap pad for increased comfort, fine webbing, and Timbuk2â??s Double-Loop CAM buckle that adjusts quickly and eliminates dangling straps. A low profile grab handle makes the messenger easy to grab and go and 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 balances the weight of your carry. Itâ??s a classic through some modern evolution, and its ready to be worn for whatever your carry needs.
