45 litres of adventure. Outstanding waterproof protection. Freedom to explore.

Discover the ORTLIEB ATRACK 45 L in Petrol, a premium waterproof backpack that combines the comfort of a technical hiking backpack with the convenient accessibility of a travel duffle bag. Designed for adventurous travellers, hikers and outdoor enthusiasts, it offers generous storage space, intelligent organisation and reliable protection for demanding journeys.

The ATRACK stands out thanks to its innovative suitcase-style opening. Instead of searching through a conventional top-loading backpack, you can open the spacious main compartment using the full-length, waterproof TIZIP® zipperpositioned against the back panel. This gives you an excellent overview of your equipment and makes packing, unpacking and accessing your essentials remarkably convenient.

With its generous 45-litre capacity, the backpack is ideal for multi-day hikes, outdoor expeditions and extended travel. The IP67 waterproof rating, waterproof welded seams and durable, PVC-free fabric help protect your belongings against heavy rain, dust and temporary immersion in water when the zipper is correctly closed.

The ergonomic carrying system features an adjustable back panel, comfortable shoulder straps, a chest strap and a padded hip belt. Designed for M–XL back lengths, the 45 L version provides a practical fit for a wide range of users. Four compression straps help stabilise your load, while multiple internal and external pockets make organising smaller items effortless.

Its distinctive Petrol colour brings a contemporary outdoor-inspired appearance to a backpack built for serious adventures. Made in Germany, the ORTLIEB ATRACK 45 L combines durable craftsmanship, innovative functionality and long-lasting reliability.
