How the other picks compare
Sailnovo 21 cu ft Soft Roof Bag
The Sailnovo 21 cu ft option halves the storage volume compared to the 40 cubic feet Mockins bag. It measures 7.09 by 13.8 by 9.84 inches when packed, making it significantly more compact. Weighing only 8.16 pounds, it is much lighter than the 15.7 pound Mockins carrier. This smaller footprint suits compact cars without roof racks where space is limited. You lose nearly half the cargo capacity, but gain easier handling and lower weight. Choose this if you need moderate storage for weekend trips rather than heavy hauling. The black color offers a discreet look. It remains a waterproof soft-shell choice for drivers who prioritize portability over maximum volume.
Mockins 40 cu ft XXL Roof Bag
This Mockins variant also provides 40 cubic feet of storage with identical 72 by 48 by 20 inch dimensions. The primary difference is the all-black color scheme versus the black and orange original. It weighs slightly more at 16.5 pounds compared to the 15.7 pound standard model. The internal volume remains unchanged for hauling large items like suitcases or sleeping bags. You get the same waterproof protection and flexible mounting for vehicles without racks. Pick this version if you prefer a monochrome aesthetic that blends with your vehicle. The added weight is negligible for most users. It serves the same function as the original, offering high capacity for travelers needing extensive roof storage without installing permanent crossbars.
Mockins 30 cu ft Soft-Shell Vinyl Roof Bag
The Mockins 30 cu ft model reduces capacity by 10 cubic feet compared to the 40 cubic feet original. It measures 60 by 43 by 20 inches, fitting smaller vehicles better. At 15.5 pounds, it is nearly identical in weight to the 15.7 pound 40 cu ft version. This size suits drivers who do not need the maximum XXL space but still want waterproof soft-shell storage. You sacrifice volume for a slightly smaller footprint. The black and orange design matches the original aesthetic. It works with cars, SUVs, and trucks without roof racks. Choose this alternative if your cargo load is moderate and you want a secure, all-weather carrier that is easier to manage on smaller roof surfaces.
Rooftop Ranger 21 cu ft Soft Shell Cargo Carrier
The Rooftop Ranger 21 cu ft carrier offers half the storage of the 40 cubic feet Mockins bag. It measures 54 by 42 by 17 inches, making it smaller and lighter at 8.5 pounds. This weight is significantly less than the 15.7 pound original. The black and gray color provides a different visual style. You lose substantial cargo space, gaining only 21 cubic feet instead of 40. This model is ideal for vehicles without roof racks where portability matters. The reduced dimensions fit smaller cars more easily. Choose this if you prioritize a lightweight, compact solution for moderate loads. It remains a waterproof soft-shell option, but sacrifices volume for easier handling and storage when not in use.
MCBD 40 cu ft Soft-Shell Roof Bag
The MCBD 40 cu ft bag matches the original capacity and height at 20 inches. However, its listed width and length are 1 inch, which appears to be a data error. It weighs 16.3 pounds, slightly heavier than the 15.7 pound Mockins. The blue color offers a distinct look compared to the black and orange original. It targets large families needing high volume storage for cars and SUVs. You get the same 40 cubic feet of waterproof space for heavy loads. The included carry bag adds convenience. Choose this if you prefer the blue aesthetic or need a soft-shell carrier for vans. It provides ample room for luggage, though the dimensional data requires verification before purchase.
