You are not deterred by longer climbs and embrace all challenges while racing 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, thus supporting your bike handling on uneven, winding trails. The backpack is spacious enough to hold change of clothes and essentials for multi-day tours, including hut stays. The main compartment can be divided into two sections. There is a base access compartment at the bottom. Hydration bladders up to 3 liters in volume can be stored in a separate compartment. The front, two-part tool compartment with mesh inserts provides excellent organization for tools and maps. Access to the weather-protected smartphone compartment 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 just as standard as the included rain cover (with reflective print) and the light holder. The "Plus" in the name stands for the variable, top-open compartment where a rain or wind jacket can be stowed during longer rides. The durable material has been equipped with Eco Finish, making it permanently water-repellent without PFC.
