You are not deterred by longer climbs and embrace all challenges while speeding downhill? Then you need this flexible backpack that will help you conquer any Alpine crossing. The innovative, ventilated Aeroflex Control back system offers you unique comfort: for good ventilation during sweaty uphill climbs, you can tighten the back system. For downhill rides, the system can be converted to a body-contact back. This brings the center of gravity closer to your body, thereby supporting your bike handling on uneven, winding trails. The backpack is spacious enough to carry change of clothes and essentials for multi-day tours, including hut stays. The main compartment can be divided into two sections. There is a bottom access pocket. Hydration bladders up to 3 liters can be stored in a separate compartment. The front, divided tool compartment with mesh inserts provides excellent organization options for tools and maps. Access to the weather-protected smartphone pocket is possible even with the rain cover on. Small items can be stored in the mesh side pockets. An adjustable chest strap, a removable helmet holder, side compression straps, an outlet for the hydration system, and holders for keys and lights are all standard features, along with the included rain cover (with reflective print) and light holder. The "Plus" in the name stands for the variable, open-top compartment, where you can stow away a rain jacket or windbreaker during longer rides. The durable material has been equipped with Eco Finish, making it permanently water-repellent without PFC.
