Capacity and Size Comparison
Storage capacity
The Mockins 40 cu ft XXL offers 40 cubic feet of interior space. The Mockins 45 cu ft XL provides 45 cubic feet. This five cubic foot difference allows the XL model to hold more gear. You can fit additional suitcases, sleeping bags, or tents in the larger bag. If you have high-volume packing needs, the XL model gives you extra room. The XXL model is sufficient for standard trips with moderate luggage loads. Choose the 45 cu ft version if you need maximum volume for extended travel or moving items.
Overall dimensions
The 40 cu ft bag measures 72 inches long, 48 inches wide, and 20 inches high. The 45 cu ft bag measures 75 inches long, 48 inches wide, and 22 inches high. Both share the same width, so they fit similarly on most roof racks. The XL model is three inches longer and two inches taller. This extra length and height contribute to its greater capacity. You should check your vehicle roof length to ensure the 75-inch bag fits without overhang. The XXL model may suit smaller roofs better.
Shell type
Both models feature a soft-shell construction. The 40 cu ft bag uses abrasion-resistant vinyl. The 45 cu ft bag uses rugged soft-shell vinyl. Both designs are flexible and conform to your vehicle roof shape. This flexibility helps them fit vehicles with or without crossbars. The material choice is similar across both sizes, focusing on durability and weather resistance. You do not need to worry about hard plastic damage to your car paint. Both bags offer a soft exterior that is gentle on vehicle surfaces during transport.
Water resistance
Both the 40 cu ft and 45 cu ft bags are fully waterproof. They feature waterproof zippers protected by flaps to keep water out. Reinforced welded seams add durability and prevent leaks during heavy rain. This triple-shield protection ensures your gear stays dry in all weather conditions. You can rely on either model for camping trips or moving in wet climates. The waterproof design is a core feature for both sizes, providing equal protection against moisture and humidity.
Weight
The 40 cu ft bag weighs 15.7 pounds. The 45 cu ft bag weighs 20.5 pounds. The larger bag is nearly five pounds heavier. This difference comes from the extra material needed for the larger dimensions. You should consider this weight when installing the bag on your roof. Heavier bags may require more effort to lift and secure. However, both weights are manageable for most adults. The lighter 40 cu ft model is easier to handle if you install it frequently.
