P.I. AUTO STORE Rooftop Cargo Carrier 16 cu ft Waterproof Roof Bag with Anti-Slip Mat — Durable, Weather-Resistant Storage

The P.I. AUTO STORE rooftop cargo carrier is a 16 cubic-foot waterproof roof bag that adds secure, weather-resistant luggage space to virtually any car.

When trunk room runs out, this soft-sided roof carrier gives you a tidy, protected place for suitcases, camping gear, sports equipment and bulky items. Built from 100% waterproof nylon with reinforced seams and heavy-duty straps, the bag is designed to stay put during long drives while protecting your gear from rain, snow, dust and road spray. It fits vehicles with or without factory roof racks and includes an anti-slip mat to reduce shifting and prevent roof scratches.

How much extra storage will I actually get?

The carrier provides about 16 cubic feet of additional capacity — roughly the volume of a medium-sized trunk. That space typically holds several soft suitcases, sleeping bags, or a mix of boxes and recreational gear.

• Capacity: 16 cubic feet for luggage, tents, coolers, or sports gear
• Holds multiple suitcases or oversized items that won’t fit inside
• Soft-sided design lets you pack irregular shapes more efficiently

Will it keep my belongings dry and protected in bad weather?

The bag uses waterproof nylon fabric, heat-welded seams and a reinforced zipper to create layered protection against moisture. Kevlar-reinforced stitching adds durability at stress points so the carrier resists tearing in wind and during loading.

• 100% waterproof nylon outer layer
• Heat-welded seams and heavy-duty zipper for additional water resistance
• Kevlar-reinforced threads at high-stress areas to prevent seam failure

How does it attach to different cars and stay secure at highway speeds?

Four heavy-duty straps fasten under the vehicle doors or around roof rails to lock the bag in place. The included anti-slip mat sits between the bag and car roof, reducing movement and protecting paintwork.

• Four robust straps with quick-release buckles for secure fastening
• Anti-slip protective mat prevents sliding and roof scratches
• Compatible with crossbars, side rails, baskets, or cars without racks

Is installation and storage manageable for one person?

Yes — set-up is straightforward: lay the mat, position the empty bag, close the zipper after loading, and fasten the straps. When not in use the carrier folds flat for compact storage in a garage or trunk.

• Simple step-by-step fitting that one person can complete
• Folds down flat for easy storage when empty
• No permanent hardware required; hooks for cars without racks available separately

Who is this for? The P.I. AUTO STORE rooftop carrier is ideal for road-trippers, families, campers and anyone who needs extra weatherproof cargo room without investing in a rigid roof box. It suits drivers who want a flexible, cost-effective way to transport bulky or extra luggage, and it works well for vehicles with or without factory racks. If you frequently pack oversized gear, travel in variable weather, or need a temporary storage solution for weekend getaways, this rooftop bag offers a practical balance of capacity, protection and portability.
