Our Messenger Bag is built to be tough. It features a water resistant truck tarp liner, waterproof YKK zippers and a dual closure system with g-hooks and hook and loop material. A padded internal laptop sleeve means this bag is equipped for bike commutes to school or work, and internal water bottle straps ensure the secure carry of your bottle. Bottom compression straps keep the bag from getting too bulky, and the padded adjustable shoulder strap is removable so it can be comfortably worn regular or goofy.
