AlltoAuto 20 Cu Ft Waterproof Hitch Cargo Bag — 600D PVC, Foldable with Straps & Lock

The AlltoAuto 20 cu ft waterproof cargo bag is a heavy-duty hitch carrier bag that protects and secures gear behind your vehicle using durable 600D PVC tarpaulin, included straps, and a combination lock.

Designed for road trips, moving day, and seasonal hauling, this hitch-mounted cargo bag makes it simple to expand your vehicle's carrying capacity without a roof rack. Built from 100% waterproof grid PVC with reinforced seams, the bag resists rain and road spray while folding into its small carry pouch for compact storage. With universal compatibility for most hitches and a 20 cubic foot capacity, it carries suitcases, camping gear, and bulky items that won’t fit inside the cabin.

How much gear can this hitch bag hold?

The AlltoAuto hitch bag provides about 20 cubic feet of interior space (60" L × 20" W × 29" H), enough for several medium suitcases or a mix of camping and travel gear. The soft-sided design lets you pack irregular shapes more efficiently than a hard box.

• Holds 4–6 carry-on sized suitcases or equivalent camping equipment
• Dimensions: 60 inches long, 20 inches wide, 29 inches tall
• Flexible interior accommodates tents, sleeping bags, and duffels

Will this bag stand up to rain and road wear?

Yes—manufactured from 600D PVC tarpaulin with grid reinforcement and high-frequency welded seams, the bag is engineered to keep contents dry in wet conditions. The material resists abrasion and punctures common on hitch-mounted loads, and the soft shell drains and rolls up when empty.

• 100% waterproof outer material and welded seams
• Durable against road spray, mud, and light impacts
• Soft construction folds into the included storage pouch

How secure and easy is it to install?

Installation uses the supplied straps and buckles that fasten the bag to most trailer hitch carriers; typical setup takes just minutes. For added theft deterrence and zipper protection, a coded combination lock is provided to secure the main opening.

• Comes with three adjustable straps and quick-release buckles
• Includes a bonus coded combination lock to secure zippers
• Universal fit for most cars and SUVs with a hitch carrier

How do I store the bag when not in use?

The soft-shell construction collapses flat and tucks into the supplied carry pouch to save space in your garage or trunk. Lightweight and foldable, it’s easy to keep on hand for spontaneous trips or seasonal storage.

• Folds down to fit inside the included storage bag
• Soft material reduces overall packed volume when empty
• Carry pouch keeps straps and lock together for quick access

Who is this for: The AlltoAuto 20 cu ft waterproof hitch cargo bag suits road trippers, families, and outdoor enthusiasts who need extra cargo capacity without a roof rack. It's also ideal for people who want a weatherproof, foldable solution that attaches quickly to most hitch-mounted carriers and adds a simple layer of security with an included combination lock.
