The Zephir 22+3 is a hiking backpack designed by the brand Ferrino, ideal for running, cycling, or hiking. Whatever the conditions, your back will stay constantly ventilated, even in hot weather. Indeed, the ""Dry Net System"" and ""Hollow Back System"" ensure this high level of breathability. This is mainly achieved through the preformed padding found on the shoulder straps, waist belt, and back panel of the Ferrino backpack. Additionally, you have several storage options in the Zephir 22+3. Besides the main compartment, you can benefit from an internal back pocket, a pocket on the waist belt, and two front pockets. The side mesh pockets are perfect for holding your water bottle and snacks. Even in the dark, the reflective strips on the backpack will make you visible for added safety. Finally, the rain cover of the Zephir 22+3 will keep your belongings dry in case of rain.
