Ortlieb's Packman Pro2 bag is perfect for exploring on or off your bike. The waterproof main compartment features a zippered pocket to keep things organized and a separated compartment for a hydration system (sold separately). Two shoulder straps, a wide waist belt, and a chest strap keep the bag secure and the mesh back pads facilitate ventilation. An outside pocket gives you more packing options and integrated helmet straps easily carry more gear. If you're out at dusk or dawn reflective accents increases visibility.
