Best waterproof commuter bag for urban Brompton cyclists.
This is the ultimate commuter companion that finally solves the awkward transition from bike rack to back. While the magnetic strap system keeps things sleek and secure on the road, you do sacrifice a bit of quick-access storage for that streamlined, waterproof profile.
