Shop newer versionSlicing through the air like a hot knife through butter, the new Thule Sonic XL roof box features a patented aerodynamic design.
- Front of cargo box features a patented AeroNose design that is pointed so box cuts through the air, helping to reduce drag and noise
- Rear of cargo box also features a patented rear-angled base design, helping to maximize trunk and hatch clearance
- Mounting system clicks when you reach the optimal hold, so you'll be on the road in seconds; can be mounted on square and round crossbars and most factory racks (see Fit List)
- Patented, dual-side openings let you access your gear from either side of the box
- Locking system features an external lock-assist knob that is easy to use; built-in safety feature means the key can only be removed when the box is fully closed

- Thule Sonic XL roof box holds 6 - 8 pairs or skis or 4 - 6 snowboards
