At 22 cubic feet of storage space, the Sonic XXL is one of the largest cargo boxes Thule has to offer.  Thule combined technology with style achieving high performance with good looks.  The aerodynamics sets the Sonic XXL apart from other boxes with a patented Aeronose design that cuts through the air, reducing drag and noise.  Ideal for those looking for a cargo box that is capable of a wide variety of uses.

Features include:

  • Dual side opening.  Get the convenience of loading or unloading from either side of the vehicle.
  • AcuTight mounting system.  Quick to install, you'll know with a click when the box is correctly installed and secure.
  • SecureLock.  Oversized so it's easy to grasp, you will know when the box is closed securely and properly.
  • Recycled material and aerodynamic design.  Where technology and performance combine, the cargo box contains up to 80% post manufactured recycled material and is designed with an upward angle at the back to allow more clearance for trucks and hatchbacks.
  • AeroNose design.  Cuts drag and reduces noise
  • Anti-torsion ribs.   Located in strategic places, these ribs help resist lifting and pulling forces, making it easier to quickly and securely open and close the cargo box.
