Optimal adaptability in a hiking pack for more comfortable day trips. The user-friendly Aeroflex Control suspension system keeps your back well ventilated during sweaty ascents and rides comfortably against your back on the way back down. The Shifting Back Length System also allows the back of the pack to be perfectly adjusted to your own torso size. An integrated zip volume expansion and practical organizer in the front pocket ensure flexibility and order. External net pockets, hydration system accessibility and practical compression straps complete its features. In addition, the Wizard 18+4 consists primarily of recycled materials – this environmentally-friendly backpack has everything a versatile hiking companion needs for your next adventure. It's made with eco-friendly, water repellent Eco Finish, which is manufactured without the use of fluorocarbons (PFC). The VAUDE Green Shape label stands for environmentally-friendly, functional products made from sustainable and bluesign® certified materials.
