The fascination of dynamic sports and high performance technology – ORTLIEB has combined both in the innovative design of the backpack COR13. The minimalist design and weight make this a pack you can carry all day long. Though the COR13 has no external frame and it is very comfortable. The padded back with ventilation channels provides efficient air circulation. The wide, comfortable hip strap fins, anatomically contoured shoulder straps and chest strap are individually adjustable, and keep the pack close to your body.

Clothing or other items may be stowed under the adjustable and removable front flap. The main compartment houses a sewn-in organizer for the inclusion of an optional hydration system( up to 40 oz or 1.1 L).
