Timbuk2 Messenger bags are designed to be worn comfortably on a bike and are distinguished by their foldover flap closure and cross-body strap. These bags are constructed of durable fabrics, including CORDURA Nylon and Weathered Canvas. The interiors are lined with waterproof TPU to help protect valuables from wet floors or rain showers. Messenger bag straps include the Double-Loop CAM buckle for easy fit adjustment, and a removable cross-strap to keep the bag stable during bumpy rides. Each Timbuk2 messenger bag has a large main compartment, plus an external front organizer for pens and wallet.
