The Thule Pack’n Pedal Large Adventure Touring Pannier is waterproof and has 26 liters of space for you to carry loads of gear. With its roll top design you can compress it into what looks like a much smaller pack that you can carry over your shoulder with the included shoulder strap. This bag fits on virtually any rack and with Thule’s vanishing hardware attachment the mounting clips store neatly in the back of the bag.
