Vango Flux 22- This is a mid-sized urban backpack that is not weighed down by additional elements such as a hip belt or gear loops. The backpack has two large compartments, a front pocket with a zipper, and two side pockets. It is convenient to use it as an office backpack since it can accommodate a laptop with a diagonal of up to 15.6 inches, the backpack has an organizer for small things, is compatible with an A4 format, and has enough space to place, for example, lunch and a thermos with tea. As more and more people prefer to commute to work by bicycle in urban conditions, given this likelihood, the backpack is equipped with a chest strap to ensure stability while riding and equipped with a hydration system. The model has a proprietary back ventilation system AirForce back system.
