Ariolimax is the scientific name for the banana slug, a resident of Pacific Northwest loam. The Ariolimax Top Tube Bag stretches out across your top tube like a banana slug, adhering with tenacity and turning unused space along the top tube into highly organized storage.

The extended design provides significantly more capacity than a traditional top tube bag while remaining stable and out of the way when the trail gets rough. Foam side stiffeners help the bag hold its shape and resist bulging, keeping your cockpit tidy and your knees happy.

Inside, a movable hook-and-loop divider lets you tailor the layout to your ride. Separate snacks from tools, electronics from layers, or open the divider completely to create one large compartment for bulkier gear. Two external stash pockets and internal mesh organizers keep frequently used items easy to find, while a bright interior lining helps you spot what's hiding at the bottom.

Built for long days, big rides, and riders who refuse to leave anything behind.
