The New Sonic Box holds are your gear with efficiency and cool style. An aerodynamic box sized to fit skis, poles or snowboards.
The Thule 633 Sonic Alpine High Gloss Roof Rack Mounted Cargo Box features a completely new design for improved performance and maximum convenience. The Sonic series utilizes Thule's new AeroNose shaping and Hi-Flow Base to reduce drag and allow air to more easily pass between the box and your roof - giving you better gas mileage and a quieter ride. The Sonic Alpine has a 10 cubic foot cargo capacity. This low profile design reduces drag and provides lower garage clearance. The Sonic Alpine is particularly well suited to carrying snow sport gear, hockey sticks, 4 - 5 pairs of skis or 2 - 3 snowboards. The Sonic Alpine's Dual-Side Opening feature allows you to load and unload your gear from either side of your vehicle. Thule's AcuTight Mounting Hardware directly attaches to most after-market and factory installed roof racks in seconds and automatically stops tightening at the correct mounting tension - taking the guesswork out of mounting your box. The Thule Sonic Alpine is available in Black or Silver.
