Comparing roof bag alternatives
Sailnovo 21 cu ft Soft Roof Bag
The Sailnovo 21 cu ft soft roof bag offers a lighter alternative for drivers who do not need maximum volume. Weighing just 8.16 pounds, it is significantly lighter than the Mockins 35 cu ft carrier at 13 pounds. The storage capacity drops to 21 cubic feet, which limits bulkier loads like large tents or multiple suitcases. Its compact dimensions make it easier to handle and store when not in use. This model suits smaller vehicles or buyers prioritizing ease of installation over sheer cargo space. If your gear fits within 21 cubic feet, this bag reduces roof profile and weight while maintaining soft-shell flexibility.
Mockins 30 cu ft Soft-Shell Vinyl Roof Bag
The Mockins 30 cu ft soft-shell vinyl roof bag provides a middle ground between the 21 and 35 cubic foot options. It retains the same 60-inch length as the original but reduces width to 43 inches and height to 20 inches. The capacity decreases by five cubic feet, making it slightly less voluminous. At 15.5 pounds, it is heavier than the original 13-pound model, likely due to reinforced materials or included accessories. This bag is ideal for those who find the 35 cu ft size too large but still need more than 21 cubic feet. It maintains the brand’s waterproof design and rack-free mounting capability for versatile vehicle compatibility.
Rooftop Ranger 21 cu ft Soft Shell Cargo Carrier
The Rooftop Ranger 21 cu ft soft shell cargo carrier is a compact, budget-friendly option for vehicles without racks. It matches the Sailnovo in capacity but differs in dimensions, measuring 54 inches long and 42 inches wide. Weighing 8.5 pounds, it is slightly heavier than the Sailnovo but lighter than the Mockins 35 cu ft. The reduced length makes it suitable for shorter vehicles or smaller cargo loads. This carrier sacrifices volume for a lower profile and easier handling. It is a practical choice for buyers who need basic waterproof protection and secure straps without the bulk of larger carriers. It fits well for weekend trips or light moving needs.
MCBD 40 cu ft Soft-Shell Roof Bag
The MCBD 40 cu ft soft-shell roof bag offers greater capacity than the Mockins 35 cu ft original. It provides five additional cubic feet of storage, accommodating larger loads like multiple suitcases or bulky camping gear.
