P.I. AUTO STORE Rooftop Cargo Bag — 16 Cubic Foot Waterproof Roof Carrier with Protective Mat

If you need extra luggage room for weekend getaways, camping trips or moving bulky gear, this rooftop carrier converts your vehicle’s roof into a safe storage area. Built from 100% waterproof nylon with reinforced seams and heavy-duty straps, the P.I. AUTO STORE Roof Bag is designed to keep luggage dry and stable while maximizing usable space without permanent roof-rack installation.

How much extra storage will this rooftop bag give me?

The carrier provides approximately 16 cubic feet of cargo space — enough for several suitcases, duffel bags, or camping equipment. Its rectangular shape and wide opening make loading and organizing simple, and the capacity is suitable for a family weekend or light moving needs.

• 16 cubic feet total volume for luggage, tents, sleeping bags.
• Wide zippered opening for easy packing and removal.
• Rectangular footprint that fits most vehicle roofs without overhang.

Will the bag stay put at highway speeds and in bad weather?

This rooftop carrier secures with four sturdy straps and includes a non-slip protective mat to prevent shifting and protect your vehicle’s finish. The material uses waterproof nylon, Kevlar-reinforced stitching and heat-welded seams, while the zipper is built for repeated use in wet conditions.

• Four heavy-duty fastening straps with quick-release buckles.
• Anti-slip protective mat reduces movement and prevents scratches.
• Triple waterproof protection: fabric, reinforced threads, welded seams.

Can I use this bag on cars without roof racks?

Yes — the P.I. AUTO STORE carrier is compatible with vehicles that have cross bars, side rails or no roof rack at all. It mounts directly on the roof using the included straps; optional door hooks (sold separately) offer additional attachment points for vehicles lacking factory rails.

• Works with roofs that have cross bars or side rails.
• Mounts to bare roofs using straps and the included anti-slip mat.
• Optional door hooks available for extra stability on rackless cars.

How simple is installation and everyday use?

Installation is straightforward: place the protective mat, position the bag, zip it closed and tighten the four fastening straps. The bag is lightweight for handling and folds flat for compact storage when not in use.

• Quick setup in minutes without tools.
• Lightweight, foldable design for easy storage in trunks.
• Durable zipper and reinforced seams for repeated trips.

Who this is for: The P.I. AUTO STORE Rooftop Cargo Carrier is made for drivers who need temporary, high-capacity storage without investing in permanent roof racks — weekend travelers, campers, small families and anyone moving bulky items. It’s especially useful for people who want a weatherproof, non-permanent solution that protects their vehicle’s finish while increasing cargo capacity.
