Breathable, durable, and comfortable - the 3D AERORISETM 40 features a completely innovative carrying system for an unprecedented carrying experience. Using 3D printing, four individual back pads are created that adapt to the body and optimally distribute weight. The open fabric structure allows for even better ventilation, significantly reducing temperature on the back. Based on body mapping, different zones are identified, which are then designed to be firmer or softer using numerous struts, depending on where more stability or cushioning is needed. This novel process saves resources as it produces minimal waste, and the tear-resistant, ultra-light main material CROSS RIP 70D is made from 100% recycled synthetic fibers. The large, waterproof main compartment can be compressed from the inside using a roll-top closure. A separate compartment on the back provides space for a hydration system or serves as secure storage for maps. To keep your essentials easily accessible, there are two zippered pockets on the backpack lid, two practical side pockets, and a small pocket on the hip belt.
