Description Backpack for MacBooks Pro 16'' and laptop 15.6'', equipped with our anti-gravity system, an elastic kind of suspension in the shoulder straps designed to reduce the weight on the shoulders and the back when your body is moving. 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. Made of high-density fabric, Marte Gravity is very well organized, both inside and out. The extra-roomy interior compartment is equipped with two padded pockets for laptops and tablets, ensuring good protection. The front side multi-tasks, providing different-sized spaces with zipper closures. Two side pockets offer the perfect place to store a water bottle and an umbrella. The back is ergonomic and features padded shoulder straps with a suspension system, trolley strap, and a security pocket. A removable rain cover, hidden in the bottom, allows you to protect your backpack in wet weather.
