When it comes to fitness training, the backpack scores points for its adaptability: the compression straps allow the backpack depth to be individually adjusted, optimizing weight distribution and increasing comfort – especially helpful when the backpack is heavily loaded. If you like, you can also make the backpack heavier and use it for everyday training. The aerobis Fitness Backpack is suitable for a variety of activities, including hiking, fitness, and office work. The special opening is particularly practical, making it quick and easy to load and unload weights. The size can be flexibly adjusted by wrapping the upper opening several times. Another advantage is its 100% waterproof nature. Several waterproof compartments with zippers protect the contents from moisture. The backpack is also ideally equipped for hiking and everyday use. Adjustable straps for the shoulders, hips and chest ensure a customized fit and a secure hold. Reinforced plastic plates provide additional stability, and a laptop compartment protects electronic devices. Everything is kept neat and robustly processed.
