The MCBD 40 cubic feet rooftop alternative list compares seven similar soft-shell cargo bags to help you find the right fit. The original MCBD bag offers 40 cubic feet of capacity and a 900D PVC waterproof shell. It includes ratchet straps, door hooks, and an anti-slip mat for secure mounting. This combination provides ample space for large loads while protecting contents from rain and snow.
You might choose a different model if you need a smaller footprint or a different mounting style. Some alternatives offer 30 or 21 cubic feet for vehicles with limited roof space. Others are optimized for specific brands like Jeep or Ford. These picks were selected because their specifications overlap with the MCBD bag in capacity, material, or vehicle compatibility. Review the dimensions and weight limits to ensure the bag fits your car's roof rack or bare roof securely.
Our top pick: MCBD 40 cu ft Soft-Shell Roof Bag.
How Each Alternative Compares
Mockins 30 cu ft Soft-Shell Vinyl Roof Bag
The Mockins 30 cu ft bag offers 10 cubic feet less volume than the MCBD, measuring 60 x 43 x 20 inches. It weighs slightly less at 15.5 pounds. This model is ideal if your roof dimensions are smaller than the MCBD’s 72 x 48 inch requirement. You get a compact, waterproof soft-shell design that fits vehicles without racks. However, you sacrifice capacity for a tighter footprint. Choose this if you need reliable weather protection but have limited roof space. It is a practical budget pick for moderate loads that do not require the massive 40 cubic feet of the MCBD.
Sailnovo 21 cu ft Soft Roof Bag
The Sailnovo 21 cu ft bag provides significantly less storage space, offering only half the capacity of the MCBD. It is much lighter at 8.16 pounds and measures smaller in overall dimensions. This soft-shell option is designed for cars without roof racks. You give up substantial volume for a lightweight, easy-to-store solution. It is best for short trips with minimal gear. If you need to transport large items, this model will not suffice. It serves drivers who prioritize low weight and easy handling over maximum cargo capacity. It is a niche choice for small loads on compact vehicles.
BagMate 23 cu ft Roof Bag – 840D PVC
The BagMate 23 cu ft bag has 17 cubic feet less capacity than the MCBD. It features an 840D PVC shell, which is a durable material, though the MCBD uses 900D. The BagMate measures 55 x 44.9 x 19.5 inches, making it narrower and shorter. It weighs 13.1 pounds. This model is suitable for vehicles without racks that need moderate extra space. You trade the MCBD’s large volume for a more manageable size for smaller cars. It is a solid alternative if you do not need to haul bulky sports equipment or multiple suitcases. It fits well for weekend trips with light luggage.
SR1 Performance 20 Cu Ft Roof Bag with Jeep Logo
The SR1 Performance 20 CuFt bag offers 20 cubic feet less capacity than the MCBD. It is designed specifically for Jeep owners and features a distinct logo. The bag measures 44 x 34 x 17 inches, fitting smaller roof areas. It weighs 8.8 pounds. This lockable soft-shell carrier is ideal for compact loads. You sacrifice significant volume for a specialized fit and lower weight. It is best for Jeep drivers with limited roof space or no rack. If you need to carry large camping gear, this model is too small. It serves those who prioritize vehicle-specific aesthetics and secure, weather-resistant storage for small items.
Mockins 40 CuFt XXL Roof Bag
The Mockins 40 CuFt bag matches the MCBD’s 40 cubic feet capacity exactly. It measures 72 x 48 x 20 inches, identical in footprint. It weighs 15.8 pounds, slightly lighter than the MCBD’s 16.3 pounds. This soft-shell vinyl option is a direct alternative for vehicles without racks. You get the same volume but with a different brand and potentially different mounting hardware. It is a strong choice if you need maximum capacity without installing roof racks. The weight difference is minimal. Choose this if you prefer the Mockins brand or if its specific mounting system suits your vehicle better than the MCBD’s.
TQGIBCX Roof Cargo Bag for Ford Escape Active
The TQGIBCX bag is designed for the Ford Escape Active and offers much less capacity than the MCBD. It weighs only 2.2 pounds, making it extremely lightweight. This model is tailored for owners without roof racks who need a simple, tool-free solution. You sacrifice significant volume for a specialized fit and ease of use. It is best for light travel needs on this specific vehicle. If you need to carry large loads, this bag is insufficient. It serves Ford Escape Active owners who prioritize convenience and low weight over high capacity. It is a niche option for specific vehicle compatibility and minimal gear transport.
