A waterproof, sustainably sourced solution for bikepacking, touring, and commuting, engineered in partnership with ORTLIEB for weight distribution, next-to-body breathability, and structural ergonomics tuned for the riding position.

The ASSOS x ORTLIEB Atrack tailors 25L of waterproof storage for use on the bike, eliminating certain features like hip wings - which would restrict posture in the saddle – and an adjustable length that ensures your hips are anchoring the load, not your back. The stabilizing shoulder and sternum straps are adjustable, and the waist strap can either be adjusted or removed altogether to suit your needs and preference.

The main compartment is completely accessible through the duffel-style zip, eliminating the struggle of digging from the top while setting up camp or fishing for one buried item. For even quicker access, external daisy chains provide attachment utility and a pair of side pockets - one secured with elastic mesh and the other with a zip closure – keep ride essentials close at hand. Items that require even more security benefit from four internal zippered pockets, and an internal compression strap helps maintain order with unruly loads.

Two final cycling-specific upgrades finish the Atrack’s cycling transformation: breathable padding across the harness system and compatibility with hydration bladders, including a hose port, which eliminates the need for bottle cages to create additional space for frame bags.

An ultra-durable, IP67 dust- and waterproof textile secures contents from trail abuse and touring wear-and-tear. Breathable, open-structure mesh padding creates cooling airflow between the harness straps and your body.

Specifically engineered for the riding position, the Atrack reduces mid-section restrictions and adjusts to protect your back from the cargo’s weight.

Complete Touring Platform: 25L of storage, including multiple zip-secured pockets and daisy-chain convenience, keep cargo secure, stable, and safe.

Eco-conscious: Sustainable sourcing and construction reduces the Atrack’s carbon footprint to 14.06kg, which can be offset by ditching the car and riding 148km.

Full Adjustability: The stabilizing straps and harness provide 360-degree fine tuning, adapting to your body and cargo needs.

Waterproof: An IP67 rating and sealed, waterproof zipper prevent ingress of trail dust, precipitation, and road spray.
