Ortlieb Velo Shopper
Velo-Shopper has a big hatch and an 18-liter interior. And you can conveniently open and close the magnetic snap buckle with one hand. Made of waterproof, abrasion-resistant nylon fabric, the Shopper can be attached to your bike rack with the proven Quick-Lock2.1 system. And then simply sling the Velo-Shopper over your shoulder with the detachable strap when you reach your destination. Go ahead and fill the Shopper to the brim because its stiffened inside construction will help to prevent crushing.
