Why this product
Why the CURT 18320 Rooftop Cargo Carrier Bag?
The CURT 18320 is a 15 cu ft weather-resistant rooftop bag at 5 lbs — CURT bringing their hitch-brand reliability to a budget roof bag. For one or two trips a year, it handles the job. The downside? Weather-resistant isn't waterproof, the fabric and zippers are entry-level, and CURT's expertise is in metal carriers, not soft goods.
