The name says it all; with the rear-ventilated Aeroflex Control suspension system, the Moab Control mountain bike backpack offers unique comfort. You can tension the suspension for excellent ventilation on sweat-inducing climbs. On the ride back down, you can convert the system into a body-contact back. This moves the center of gravity for your load closer to your body, which supports stable bike handling on uneven trails. The shifting back length allows the shoulder strap attachment to be adjusted perfectly to your back length. The comfortable waist belt and sternum strap provide a perfect fit with optimal freedom of movement on your bike. The mountain bike backpack is divided into three compartments: a large main compartment for rainwear and provisions, a valuables compartment with internal zip pocket and a tool compartment on the front of the backpack, where everything you might need for a breakdown can be well organized and easily accessed. The helmet holder can be neatly stowed in the lower front of the pack, while a small pocket on the right hipbelt wing provides ample space for your money or a snack. Other features include side stretch pockets, a separate hydration bladder compartment, compression straps at the sides, a loop on the strap for sunglasses and a rain cover that is found in the separate bottom compartment. The bluesign certified, recycled material of the Moab Control 20 is made with eco-friendly, water repellent Eco Finish manufactured without the use of fluorocarbons (PFC). The VAUDE Green Shape label stands for environmentally-friendly, functional products made from sustainable materials.
