For many people, uncomplicated travelling and simply being on the road is an expression of individual freedom. The design of Shell picks up on this need and defines the backpack as a multifunctional companion. Shell is highly versatile and allows changing its size as needed. The design of this backpack combines the ergonomics and advantages of a large travel or hiking backpack with the portability and minimalism of a backpack for daily use. Its volume is adjustable and can be increased from 22 to 40 litres. This is made possible thanks to an innovative construction that combines a compression side system and a front webbing with a kangaroo pocket for storing things like documents. Based on the principle of a compression-based wardrobe, the backpack allows packing up to 20 per cent more than usual, if necessary. The backpack is therefore suitable for a wide array of activities from short to week-long trips. Users can unpack it easily and then comfortably hang up the part with their wardrobe as well as the accompanying toiletries pouch. This backpack impresses with its sophisticated functionality and innovative approach towards organising. Moreover, it is very light and weather-resistant. Its creation impressively embodies the aspects of durability and sustainability, which it also owes to the use of recycled post-consumer origin materials.
