Assuming that Vaude named the Wizard 30+4 after the English word for wizard or sorcerer, there must be something to it. And there is! In fact, quite a lot: The "+4" in the name of the Wizard 30+4 refers to the additional volume in liters that can be added to the base volume of 30 liters through a zipper that runs around the pack. The length of the shoulder straps is also adjustable, allowing for customization of the back length. These can be individually adjusted via a Velcro closure on the back panel from size S to XL. The mesh ventilation of the daypack works in the same way. Depending on the need for ventilation and the desired pack volume, the back panel can be shaped accordingly, whether more ventilation or a closer fit is preferred. This makes even a strenuous ascent a breeze. The front pocket of the backpack spans the entire area and provides additional storage space. The available storage is divided by a separate bottom compartment, allowing for organized gear. However, the daypack can also be used without separation, providing a larger main compartment. The rain cover is conveniently stored in a bottom compartment, but the material is already water-repellent, keeping out a few drops. Thus, the Wizard 30+4 from Vaude is a great companion for hikes, challenging summit tours, or even in everyday life and on longer trips as a supplement to a travel bag.
