Ortlieb x Assos Atrack Backpack 25L

Waterproof Atrack Backpack 25L offers rugged organization for adventure-ready travel

What Our Gearhead® Experts Are Saying:

"I’ve taken this thing through some truly gnarly rain and muddy trails, and it holds up like a champ. That waterproof zipper is legit. Plus, the side-loading design is a game-changer for quick gear access without digging through the top."

When the weather doesn’t cooperate, the Ortlieb x Assos Atrack Backpack 25L rises to the occasion. Designed in Germany with a collaborative aesthetic between Assos and Ortlieb, this waterproof pack blends function and style in a trail-tested silhouette. From rugged bike commutes to rainy trailheads, it’s built to move through it all. With a TIZIP® waterproof zipper, abrasion-resistant PS33 fabric, and a seam-welded design, every detail works to keep your gear protected and your mind on the journey ahead. The side-access main compartment makes for easy loading and fast access to essentials, while the adjustable back panel, ergonomic shoulder straps, and wide padded hip belt ensure comfort no matter how loaded your kit is. Inside, four zippered mesh compartments keep gear organized, and the external mesh pockets and daisy chains offer versatile stash options for water bottles and overflow essentials.
