Hayashi shows true greatness with the “Giant WKF†backpack. In addition to the 56 cm long main compartment, you can unfold another approximately 30 cm long case using a circumferential zip in the stable base. This has a full mesh insert on the back so that even wet and dirty things can be transported in the “Giant WKF†without any problems. The carrying system is equipped with padded contact pads, which optimizes the contact surface. Numerous drawstrings offer sufficient stability to comfortably shoulder the “Giant WKF†even when it is full. With its sporty design and multiple detailed solutions, the Hayashi sports backpack not only accompanies you reliably to the next sports event but also cuts a fine figure on a world discovery tour.
