Product Description The Atrack BP backpack by ORTLIEB - outdoor backpack for bikepacking The is the bikepacking version of the Atrack backpack family and is characterised by clever details for cyclists. These include, for example, a helmet mount, the reduced hip belt without hip flaps and a compact back padding that ensures freedom of movement. The material used is waterproof, robust and abrasion-resistant and therefore perfectly suited for using outdoors. The special position of the waterproof TIZIP zip, which is positioned on your back while carrying, keeps the carrying system and shoulder straps clean when opening the bag, preventing unwanted access. There is no need to rummage around for the items lowest in the bag, and four inside pockets and a compression strap ensure clear organisation. In addition, you have the option of attaching a drinking system to it; there is a hermetic passage for your drinking tube. Additional accessories or compression straps can be attached to the daisy chains. The back system is continuously adjustable, the ergonomic shoulder straps are equipped with a chest strap and the hip strap can be removed when not in use. Note: To achieve protection class IP 67 (dust proof, protected against ingress of water when temporarily submerged), the zipper must be completely closed.
