The Timbuk2 Classic Messenger Bag is the culmination of 25 years of cycling expertise, design innovation, and customer feedback. Slightly revamped, the Classic Messenger Bag now features Cordura nylon instead of ballistic nylon. Cordura nylon is lighter, stronger, and more water-resistant than the ballistic nylon previously used. In addition, this messenger bag features a waterproof TPU liner to protect the bag's valuables from soaking rain and splashes. This messenger bag features an exterior front and Napoleon pocket for quick-access to your keys, wallet, phone, and other small accessories. The large interior compartment features dual stretch pockets for holding water bottles or laptop chargers. A back slash pocket sits inside of the main compartment, giving you a place to secure a laptop, tablet, notebook, or loose papers. Holding small accessories, an interior organizer features small pockets and a larger zippered area for compartmentalizing your stuff. Fully adjustable, the shoulder strap easily conforms to your upper body, and it features an improved airmesh design to enhance air flow and comfort. Compression straps (S,M,L only) prevent the bag's contents from jostling around, also working to cinch a jacket or sweater for added versatility.
