The Blackburn Barrier Handlebar Bag is about as far as you can get from the simple basket you had on your bike as a kid, but it does many of the same things better. Watertight down to the zippers, the Barrier carries a generous 7.5 liters of stuff and keeps it within easy reach when you're on the bike. Essentials like your phone/GPS and map can be seen through the transparent map case. The bag detaches in seconds with a special quick release mounting system, and includes a stowable shoulder strap. Secure, dry, and at your fingertips - the perfect handlebar bag for every trip from day tours to transcontinental marathons.
