Mockins 20 CuFt Waterproof Cargo Bag for Hitch Carrier - Durable

In this review of the Mockins 20 CuFt Waterproof Cargo Bag for Hitch Carrier, the bottom line is simple: it is a practical, heavy-duty solution for drivers who need extra outdoor storage without a hard case. Designed as a hitch-mounted or truck-bed soft carrier, the bag's single biggest selling point is its weatherproof construction and roomy 20 cu ft capacity that handles duffels, tents and camping gear. The review focuses on real-world durability, how well the straps and seals keep gear secure, and whether the kit of accessories makes it ready for long trips.

Key Features

• 20 cu ft capacity: The 60in x 20in x 29in volume provides ample space for backpacks, sleeping bags and multiple duffel bags for weekend trips.
• Waterproof 500D PVC fabric: Built from heavy 600g 500D PVC tarpaulin woven polyester, the shell and seams resist soaking rain and road spray to keep contents dry.
• Protected zippers and flap: Waterproof zippers sit under a 2in flap with 5.5in Velcro closures to minimize water entry during downpours.
• Included securing gear: The kit ships with buckle straps, spring-loaded ratchet straps and reinforced loops to keep the bag stable on a hitch carrier or in a truck bed.
• Security and storage: A combination lock is included for theft deterrence and a carry case keeps the bag compact when not in use.
• 10-year limited warranty: Backed by a long warranty that reflects confidence in the materials and construction.

Who It's For

The Mockins hitch carrier bag is best for outdoorsy drivers who need a weatherproof, removable storage option for road trips, camping, or seasonal gear overflow. It fits most cars and SUVs with a cargo basket and doubles as a truck bed soft-shell solution for people who prefer a flexible, low-cost alternative to a hard cargo box.

It is less well suited to buyers who require a rigid lockable trunk, aerodynamic rooftop storage, or who regularly haul very heavy or sharp equipment that could damage soft fabric; those users should consider hard cases or specialized cargo boxes instead.

Pros & Cons

Cons

• As a soft-shell bag it does not offer rigid protection against heavy impacts or sharp objects.
