Backpack for 15.6-inch laptops and 16-inch MacBooks Pro, 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.Features:- AGS, Anti Gravity System: thanks to the elasticity of the shoulder straps you'll feel less weight on your shoulders, improving your posture- Made with high-density fabric- Well-organized pockets- Security pocket on the back- Padded shoulder straps equipped with a suspension system- Ergonomic back- Removable rain cover- Cords with all-over pattern- Two padded interior pockets for laptops and tablets- Made with high-density fabric
