Description
An expandable laptop backpack, waterproof, from 20 to 35 L
This modern expandable laptop backpack combines elegance and function to go with you through your busy days. With its expandable construction, it switches in an instant from a flat, elegant format to a large, practical one by gaining 10 cm in depth. With a built-in USB port, it lets you charge your phone easily on the move. Made with a waterproof patent leather material, it protects your belongings effectively from damp. Its expandable capacity of 20 to 35 litres, its multiple compartments and its well-thought-out pockets give optimal organisation, whether for work, travel or daily commutes. Its understated, professional design suits women and men equally well. It measures 46 x 30 x 14 cm and expands to 24 cm.
An ideal backpack for your daily journeys
With its ergonomic adjustable straps, its padded back and its tough fabric, this bag gives excellent carrying comfort even when loaded. Compact yet spacious, it can hold a laptop and everything you need for a full day. With its unisex design and elegant business style, it is also an expandable business backpack.
