With its classic look and roll up functionality, it's hard to beat these Roll Up Panniers by Brooks. Rolled up on the rack, this bike bag is sleek and out of the way but can still stow a few small daily items like a lock, tool kit, and jacket. When unrolled, the bags have enough space to hold groceries and other items from a spontaneous shopping stop on your way home. There's also an elastic strap on the top to stash a few more additional items when the bags themselves are full up with goodies.
The bags are made of water resistant cotton with leather finishing and attach to most racks with a width between 10 and 15 cm.
