Bontrager's Handlebar Bag carries your essentials right on your bars so they're super easy to reach. It offers 280 cubic inches of carrying capacity and attaches to most handlebars on road, mountain, and hybrid bikes. It features a large main compartment with a zip pocket on the front flap. And, the front flap snaps open to reveal a waterproof, transparent map case. There's also a hidden zip pocket for your valuables, too.
