Description

The practical cargo solution for the back of your car

With Thule Onto 2, you get lots of loading space with easy access – at the rear of your car! Keep the roof free for maximum mileage or to carry other loads. Or just spare your back from having to lift onto the car roof. This functional 300L cargo box is easily attached to the towbar.

Water-resistant fabric

The Thule Onto 2 features a water-resistant finish made without intentionally added PFAS, designed to help keep water and dirt from adhering to the exterior fabric. To maintain performance, clean the bag gently with mild soap and water—avoid using a high-pressure washer. Allow the bag to dry completely before collapsing it for storage. If the water-resistant properties diminish over time, refresh the surface with a water-resistant spray treatment available at outdoor retailers.

Size guide

We recommend that the width of the cargo carrier does not extend beyond the outer edges of the vehicle.
