The Thule Motion 3 XXL Rooftop Cargo Box offers a spacious solution for those in need of additional vehicle storage. Its standout feature is the 21 cubic feet of storage space, making it ideal for long trips or when transporting bulky items. The aerodynamic design, with its wing-shaped profile, aids in reducing drag, potentially improving fuel efficiency during travel.

One of the significant advantages of this cargo box is its user-friendly installation.

The material used is aluminum, contributing to durability, although the large size and weight (35 kilograms) might make handling a challenge for some users. Despite this, its compatibility with a wide range of vehicles makes it a versatile choice for many.
