RoofPax Rooftop Cargo Bag XXL 28 cu ft — Waterproof, Heavy-Duty with Door-Hook Straps

RoofPax XXL is a 28 cu ft heavy-duty, fully waterproof rooftop cargo bag that secures to vehicles with or without roof racks using a patented door-hook mounting system.

Take more gear without sacrificing interior space: this large-capacity RoofPax rooftop carrier is built for road trips, outdoor adventures, and family travel. Constructed from reinforced, weather-ready materials and designed to fasten securely on SUVs, sedans, and trucks, it includes the straps, hooks, lock, and storage sack you need to load, protect, and transport bulky luggage on top of your vehicle.

How does RoofPax attach safely to my car?

RoofPax uses a patented mounting approach that avoids routing straps through the cabin. Four purpose-built door-hook straps clamp under doors or onto crossbars when available, so the bag stays anchored without interior straps that can interfere with passengers.

• Includes 4 patented door-hook straps for secure external attachment
• Works with vehicles that have roof racks, raised rails, or no rack at all
• Heavy-duty buckles and reinforced webbing resist slippage during travel

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

Yes — the RoofPax XXL is engineered to resist rain and road spray. Multiple layers of protection, tight seams, and a dual-zipper design minimize water entry so clothing, camping equipment, or soft luggage stays drier than with basic rooftop covers.

• Water-repellent coated fabric with double-seam construction
• Dual zippers plus Velcro strap covers for extra weather blocking
• Heavy-duty zipper hardware designed for repeated use and longevity

How much gear can the 28 cu ft bag hold and how easy is loading?

The XXL size accommodates bulky items — think duffel bags, sleeping bags, tents, or several suitcases — so you can free up interior passenger space. A wide top opening and included storage bag make packing and carrying the rooftop cargo easier before and after trips.

• Generous 28 cubic feet capacity for larger family loads or outdoor gear
• Wide-mouth opening simplifies packing and accessing items
• Includes a robust storage sack to keep the carrier stored compactly when not in use

What comes in the box and what support is offered?

RoofPax supplies everything needed to mount and secure the carrier so you can install it right away. The product is backed by targeted warranties for key components and responsive customer service if you need setup help or have concerns.

• Package includes the rooftop bag, 4 patented door-hook straps, 10 heavy-duty tie-down straps, and 4 extra hooks
• Combination security lock included for zipper protection
• Lifetime zipper warranty, 5-year fabric warranty, and 24/7 customer support

Who is this for: The RoofPax XXL 28 cu ft rooftop carrier is made for families, road-trippers, and outdoor enthusiasts who need reliable, large-capacity storage without adding a permanent roof box. It’s especially useful for drivers who want a weather-resistant, heavy-duty solution that mounts externally and fits vehicles with or without roof racks.
