It's true there are Smartphones without a headphone socket and therefore headphones without cables. For all other models, this backpack provides a practical cable head plug opening. STEP L is also sprinkled with all types of customer-orientated and practical functions and compartments. Tickets go in the front zipper pocket. The newspaper goes into the compartment. The drink bottle is ready to grab in the mesh compartment and the spacious main compartment is full of books and folders. Not the case? Then the draw straps on the STEP L backpack make it as slim as possible. By the way: Anyone who would like this light, colourful backpack a little smaller will be happy about the more compact STEP M. • Capacity: 22 litres • IATA cabin baggage compliant • Pantone PMS Colour Code: Black: PMS Black C Navy: PMS 2767 C Red: PMS 1795 C White: PMS White C Apple Green: PMS 368 C Cyan: PMS 3538 C • Product Dimensions: Width: 34cm Height: 49cm Depth: 18.5cm • Spacious two-way zipper main compartment and insert pocket • Lateral lashing strap • Zipper front pocket with two insert pouches • Reflective strap on the front • Lateral mesh pouches • Headphone opening • Padded shoulder straps with height-adjustable, elastic chest strap • Padded back
