TANX Car Roof Bag Rooftop Cargo Carrier 21 cu ft — 100% Waterproof with Anti-Slip Mat & Straps

The TANX Car Roof Bag is a 21-cubic-foot, 100% waterproof rooftop cargo carrier that fits any car and includes straps, door hooks, an anti-slip mat, a luggage lock and a storage bag.

This soft-shell rooftop carrier expands vehicle storage without permanent racks or drilling. Built from heavy-duty PVC tarpaulin and reinforced grid fabric with sealed seams, the TANX roof bag keeps luggage dry and resists tears on long drives. The kit comes complete with an anti-slip base, twelve reinforced straps, six door hooks and a compact storage pouch so you have everything needed for weekend trips, family vacations or outdoor gear transport.

How well does this roof bag protect gear in bad weather?

The TANX roof bag uses 700D PVC tarpaulin and high-frequency seam welding to create a fully sealed waterproof barrier. That construction prevents rain and snow from reaching your belongings while the tough outer fabric resists rips and abrasion from road use.

• 100% seam-sealed construction against moisture intrusion
• Heavy-duty, tear-resistant PVC and grid material
• Zippers covered and secured with included combination lock
• Suitable for rainy, snowy, and dusty conditions

Will this bag fit my vehicle and stay put during travel?

The design works on cars and SUVs with or without factory roof rails — simply place the anti-slip mat between bag and roof and secure with the straps and door hooks. The 12 reinforced straps plus six door hooks create a vibration-resistant hold; the anti-slip mat helps protect the paint and prevents lateral movement.

• Universal fit for most sedans, hatchbacks, crossovers and SUVs
• Anti-slip mat protects vehicle finish and improves grip
• 12 reinforced straps and 6 door hooks for a stable load
• Compact setup in minutes without tools or permanent hardware

How much can I pack and how does loading work?

With 21 cubic feet of internal space (51" L x 40" W x 17" H) the TANX carrier holds multiple suitcases, camping gear, strollers, or sports equipment to free cabin room. The soft-shell profile makes it easy to compress or shape the bag around bulky items, and when empty it folds down into the included storage bag for neat stowing.

• 21 cu ft capacity holds 4–6 standard suitcases or equivalent gear
• Soft-shell flexibility accommodates oddly shaped items
• Folds small into the supplied storage pouch when not used
• Includes a bonus combination lock to secure zippers

Is setup and removal straightforward for occasional users?

Yes — the TANX bag was designed for quick installation and takedown so occasional travelers can load and depart without fuss. Clear strap routing and the anti-slip mat shorten the setup time, while the soft material reduces the need for heavy lifting and bulky fittings.

• Tool-free installation in minutes with step-by-step strap routing
• Soft construction reduces awkward lifting and bulk
• Comes with a dedicated storage bag for off-season storage
• Complete kit includes straps, hooks, mat and lock

Who is this for? If you need dependable extra cargo space for family travel, weekend outdoor trips, moving small loads, or freeing up interior seats, the TANX 21 cu ft roof bag is engineered for those priorities. It suits drivers who want a weatherproof, tear-resistant, and portable rooftop solution that installs without permanent hardware, keeps gear secure, and stores compactly when not in use.
