How these alternatives differ
MeeFar 15 cu ft Roof Bag
The MeeFar 15 CuFt Roof Bag is significantly smaller than the Mockins, offering 15 cubic feet versus 50. Its dimensions are 44 by 34 by 17 inches, making it suitable for compact cars where the 85-inch Mockins would overhang. You give up massive volume for a more manageable footprint. This option works best for solo travelers or couples with light luggage who cannot support the larger Mockins load. It remains a rack-free solution, but the reduced size limits gear capacity. Choose this if your vehicle roof is small or if you prioritize a lower profile over hauling bulk items like tents and multiple suitcases.
FIVKLEMNZ 30 Cubic Feet Roof Bag
The FIVKLEMNZ 30 CuFt Roof Bag provides a middle ground between the small MeeFar and the large Mockins. With 30 cubic feet and dimensions of 60 by 60 by 20 inches, it offers substantial space without the extreme 85-inch length of the Mockins. This square shape may fit better on wider SUV roofs. You trade 20 cubic feet of capacity for a more versatile footprint. It is ideal for families who need more than 15 cubic feet but find the Mockins too long for their vehicle. The 12-pound weight is lighter than the Mockins, making installation slightly easier while still providing ample room for weekend trips.
Sailnovo 21 cu ft Soft Roof Bag
The Sailnovo 21 CuFt Soft Shell Roof Bag is much lighter than the Mockins, weighing only 8.16 pounds compared to 18 pounds. It offers 21 cubic feet of space, which is less than half the Mockins capacity. Its compact storage dimensions are 9.84 by 7.09 by 13.8 inches, making it easy to store when not in use. You sacrifice volume for portability and ease of handling. This bag suits drivers who need moderate storage for clothes and small gear but do not require the heavy-duty, high-capacity haul of the Mockins. It is a practical choice for those who value lightweight design and compact packing over maximum cargo space.
RoofPax 19 cu ft Polyester Roof Bag
The RoofPax 19 CuFt Polyester Roof Bag offers 19 cubic feet of capacity, significantly less than the Mockins 50 CuFt. Its dimensions are 47.2 by 35.4 by 19.8 inches, fitting well on smaller vehicles. It weighs 12.4 pounds, which is lighter than the Mockins. This bag is designed for drivers who need reliable waterproof storage without the bulk of a 50 CuFt bag. You give up substantial volume for a more manageable size and weight. It is a good alternative for those who find the Mockins too large or heavy. The polyester shell provides weather resistance, and the design focuses on secure installation for moderate loads rather than extreme capacity.
Asinking 20 cu ft Waterproof Roof Bag
The Asinking 20 CuFt Waterproof Roof Bag provides 20 cubic feet of space, far less than the Mockins 50 CuFt. Its dimensions are 52 by 40 by 18.5 inches, offering a more compact profile. It is lockable, adding a layer of security that the Mockins also provides. You trade 30 cubic feet of capacity for a smaller, easier-to-manage bag. This option is suitable for drivers who need moderate storage and prioritize paint protection and waterproofing over high volume. It fits vehicles where the 85-inch Mockins would be impractical. The Asinking bag is a secure, weatherproof choice for those who do not need to haul large items like tents or multiple suitcases.
BagMate 23 cu ft Roof Bag – 840D PVC
The BagMate 23 CuFt Roof Bag offers 23 cubic feet of capacity, less than half of the Mockins 50 CuFt. Its dimensions are 55 by 44.9 by 19.5 inches, making it shorter and narrower than the Mockins. It weighs 13.1 pounds, which is lighter than the Mockins 18-pound bag. This bag is ideal for moderate loads on vehicles without roof racks. You give up significant volume for a more versatile size and lighter weight. It is a good alternative for those who find the Mockins too large or heavy.
