Bike waterproof messenger bags are the stylish bag of choice for many urban cyclist. These comfortable shoulder bags rest diagonally across a rider's back and typically have a stabilizing strap across the chest to keep the bags secure while riding. They are well-known for quick cargo accessibility due to their one-shoulder design, which allows a rider to slide the bag from back to front, for easy loading without having to take the bag off. With the multiple shapes and colors available, bike messenger bags have lots of personality while being highly functional for the daily tote-n-ride. With the ease and comfort of the messenger bag, it's no wonder they have sustained such a long history. They began as mail carrier bags for the Pony Express riders in the nineteenth century, resurfaced in the 1950's high-fashion shoulder bag scene, and have continued to make an impression ever since as a utilitarian bag used by active enthusiasts with places to be and stuff to carry. Made to be ultra durable, they are typically constructed from high denier Cordura, the heavy-duty fabric which offers toughness while being highly water-resistant or waterproof. In most cases, the fabric is completely waterproof, but some design features like stitched seams or outer pockets, will dub the bag as water resistant.
