Thanks to its carrying system and flat build similar to that of a vest, the backpack sits close to the body and wont shift while youre riding on bumpy trails. It sits high on the upper back, so you have unrestricted freedom of movement and easy access to the jersey pockets. Despite its extremely slim profile, it has enough room for a 1.5 L hydration bladder, provisions, and a rain jacket.A compression system further reduces unnecessary bulk. The backpack is made from recycled, PFC-free nylon taffeta, which is very lightweight yet very durable. Airy mesh at the back absorbs moisture and dries fast. Both shoulder straps have two practical zip pockets for valuables as well as two elastic mesh pockets for snacks or drinks. Thanks to the magnetic clip at the upper sternum strap, the drinking tube is easily accessible even while youre riding.Key Features:Airo flexBody huggingHydration bladderAir stripe systemKey holderMesh ventilationMagnetic tube clipHydration system compartmentCompressi
