Constructed from impact-resistant ABS, the case is designed to resist UV exposure, rain, and road debris while maintaining a glossy exterior. The dual-side opening design lets you load bulky items from either side, and a key-lock system helps secure gear when parked or on the move. The gas struts keep the lid propped during loading, enabling smoother organization on busy mornings.
JEGS Rooftop Cargo Carrier — 18 Cu Ft
JEGS offers a high-capacity 18 cubic feet hard-shell cargo carrier designed with a weatherproof interior and an aerodynamic outer shell to improve fuel efficiency. Interior dimensions measure 57 L x 38.5 W x 17.75 H inches, providing ample space for luggage and bulky items. A four-corner locking system, along with a front latch and weather-tight seal, emphasizes security and weather protection. The carrier supports loading from either side for convenience, making it easy to access items when parked in tight spaces or crowded lots.
Sailnovo Rooftop Cargo Carrier Roof Bag — 20 Cu Ft
This soft-shell bag delivers 20 cubic feet of storage using three layers of 1000D Oxford cloth with waterproofing, offering a flexible alternative to hard shells. It folds into a compact storage bag when not in use, making it ideal for occasional travelers or seasonal users. The bag includes six reinforced straps, six door hooks, and two long luggage straps to secure the carrier firmly. Note that it is not suitable for vehicles with sliding doors, and the fabric’s waterproofing helps protect contents from rain or dew during trips.

This 13-cubic-foot hard-shell carrier balances capacity with compact exterior dimensions, ideal for smaller SUVs or crossovers. Made from durable ABS, it resists weather and general wear. The double-sided opening enables convenient loading from either side, while a sturdy support arm keeps the lid open securely during access. The box is designed for universal crossbar compatibility and provides robust protection for luggage and gear against rain, wind, and road spray.
GarveeTech Rooftop Cargo Box Carrier — 14 Cu Ft
This GarveeTech model offers a dual-side opening design with a 12 to 14 cubic feet storage range, depending on the configuration, and a 165-pound capacity. The ABS shell provides weather resistance and durability while a low-profile aerodynamic shape helps reduce drag and noise. The universal fit is compatible with most roof racks, but users should verify crossbar width and mounting guidelines prior to purchase to ensure a proper fit for their vehicle.
Buying Guide: Key Considerations For Choosing A Roof Cargo Box
- Capacity vs. vehicle size: Bigger boxes offer more storage but can affect fuel efficiency and handling. Match capacity to typical trips and cargo style (luggage, gear, or groceries).
- Opening style and accessibility: Dual-side openings simplify loading bulky items and reduce emptying time on trips.
- Material and weather resistance: ABS hard shells provide weatherproof protection; soft-shell bags are lighter and flexible, ideal for seasonal use but may offer less protection.
- Mounting compatibility: Check crossbar width, load rating, and vehicle roof structure. Ensure universal fit or vehicle-specific guidance is followed.
- Security features: Look for key locks, robust latches, and durable hinges to protect contents when driving and parked.
- Ease of installation: Some models include gas struts or quick-release clamps to simplify mounting and removal after trips.
- Aerodynamics and noise: Sleek, low-profile designs can reduce wind resistance and cabin noise, improving overall comfort on long drives.
- Maintenance and warranty: UV resistance and waterproof materials extend durability, while warranties provide long-term protection for your investment.
When selecting a roof cargo carrier, consider how often you’ll use it, your typical cargo types (soft bags vs. rigid luggage), and whether you prioritize maximum capacity or quick, easy access. Confirm compatibility with your roof rack and vehicle roof clearance to ensure a secure, stable fit.
