Its hard to beat the storage capacity and ease of use that panniers offer when you're commuting by bike, but there's no doubt that they can pose some challenges, too. Namely, off-bike carrying. Some brands offer shoulder straps to enable briefcase-style slinging, but designers at Ortlieb weren't content with just the simplest solutions -- that's why they've crafted the Pannier Carrying System. This device quickly converts your pannier into a backpack, with a thermally molded foam back pad to take the pressure off, and padded, comfortable shoulder straps that keep things comfortable as you make your way on foot. The system can be connected to assorted Ortlieb panniers, including the Front-and-back rollers, bike packer, sport packer, bike tourer, velo-shopper, and bike shopper, enabling you to get the most out of your panniers when you leave the bike behind.
