The function of the anti-gravity system, in addition to improving your posture and reducing the effort exerted, specifically reduces the stiffness of your back and neck muscles, evenly distributing the backpack''s weight between your shoulders and your hips. Sole Gravity, equipped with an extra-roomy interior compartment is made with high-density fabric. The two padded inner pockets for laptops and tablets, and the two roomy front pockets of different heights, help you keep everything well-organized. In addition, two expandable side pockets with zip closures offer even more space for vertical accessories. The back is ergonomic and features padded shoulder straps with elastic suspension, a trolley strap, and a security pocket. A removable rain cover, hidden in the bottom, allows you to protect your backpack in wet weather.
