45 litres of freedom. Complete waterproof protection. One backpack for every adventure.

Discover the ORTLIEB ATRACK 45 L, a premium waterproof adventure backpack designed for travellers who demand exceptional durability, intelligent organisation and reliable protection in challenging conditions. Combining the ergonomic comfort of a technical hiking backpack with the accessibility of a travel duffle, the ATRACK offers a truly versatile solution for trekking, expeditions, outdoor sports and international travel.

Its standout feature is the innovative suitcase-style opening. Unlike conventional top-loading backpacks, the ATRACK features a large, waterproof TIZIP® zipper positioned along the back panel. This clever design allows the entire main compartment to open for convenient packing and easy access to your belongings. The back-facing zipper also makes unauthorised access more difficult while the backpack is being worn.

With a generous 45-litre capacity, the ATRACK provides plenty of space for clothing, outdoor equipment and travel essentials. Its IP67 waterproof rating, PVC-free technical fabric and waterproof welded construction help keep your belongings protected from rain, dust and temporary immersion in water when the zipper is properly closed.

Designed for comfortable carrying, the backpack features a continuously adjustable back system, ergonomic shoulder straps and a wide, padded hip belt. The 45 L version accommodates M–XL back lengths, making it suitable for users who need a larger carrying system. Four compression straps help stabilise the load, while internal and external pockets keep essential items organised.

Finished in timeless Black and manufactured in Germany, the ORTLIEB ATRACK 45 L delivers an outstanding combination of adventure-ready protection, practical design and long-lasting quality.
