Why this product
Why the Rightline Gear Sport 3 Car Top Carrier?
Here's the thing — the Sport 3 is one of the most popular rooftop bags sold, and for good reason. At 18 cu ft, 8.6 lbs, waterproof, works without crossbars, and folds flat for storage. For the price-to-capacity ratio, it's hard to beat. The downside? Soft construction means no security, the shape shifts at speed, and waterproofing degrades over time with UV exposure.
