MIDABAO 12 cu ft Waterproof Roof Top Carrier Bag — Foldable Soft-Sided Car Cargo Bag with Coated Zippers & Anti-Slip Mat

MIDABAO's 12 cubic-foot waterproof roof top carrier is a soft, foldable cargo bag that expands vehicle storage and shields gear from rain, dust and road spray.

Whether you're heading out for a weekend trip, loading camping gear, or need extra cargo space for moving items, this roof bag gives you a weather-resistant carrying solution that stores flat when not in use. Built from rubber-laminated nylon with a PVC coating and heavy-duty straps, the MIDABAO carrier mounts to cars with or without racks and includes a storage pouch plus an anti-slip mat for safer attachment.

How much extra cargo can this rooftop bag hold?

This MIDABAO carrier provides roughly 12 cubic feet of usable volume, suitable for luggage, camping equipment, or bulky purchases that won’t fit inside the cabin. Its soft-sided build makes it flexible for odd-shaped items while still packing down compactly when empty.

• Overall dimensions: approximately 41" × 35" × 17"
• Capacity: listed as 12 cubic feet for practical cargo
• Soft-sided design accommodates irregular items without rigid restraints
• Folds into the included storage bag for compact stowing

Is the MIDABAO roof bag truly waterproof and weatherproof?

The shell uses rubber-laminated nylon with a PVC coating both inside and out, plus coated zippers, to resist rain, road splash and dust better than basic water-resistant designs. While it’s built to keep gear dry in typical wet conditions, always secure seams and zippers before heavy storms for best protection.

• Double-coated PVC surface for enhanced water resistance
• Coated zippers to reduce water intrusion at openings
• Soft material reduces sharp-edge puncture risk compared with rigid boxes
• Anti-slip mat included to help prevent shifting in transit

How does installation and security work on cars with or without roof racks?

Installation is straightforward: the bag includes four wide, tough straps plus two long tie straps that route under crossbars or around the vehicle to secure the load. MIDABAO recommends fastening on all four sides when possible; fewer anchor points require extra caution and careful strap routing to prevent movement.

• Includes 4 wide straps for primary securing and 2 long straps for wrapping
• Designed to attach to roof racks and also mount on bare roofs with straps
• Anti-slip mat helps keep the bag from shifting on smooth roof surfaces
• Soft form allows snug fitting to shaped roofs and crossbars

What practical features help when the bag is not in use or during travel?

The carrier folds flat and fits into the supplied storage pouch to save trunk or garage space when not needed. During trips, the flexible material makes it easier to load awkward items than rigid rooftop boxes, and the included straps and mat streamline setup and stabilizing.

• Folds down into a compact storage bag (13" × 10" × 7")
• Soft construction eases stuffing, compressing and packing
• Durable straps and hardware for repeated mounting cycles
• Lightweight compared with hard-shell rooftop boxes for fuel efficiency

Who is this for? Drivers who need occasional extra cargo space—families on road trips, outdoor enthusiasts, shoppers with oversized purchases, or anyone with limited trunk room—will find the MIDABAO 12 cubic-foot rooftop bag a practical, weather-resistant option. It suits vehicles with roof racks best, but can be used on bare roofs with careful strap placement; when you want an easy, stowable, and protective way to carry more gear without a permanent rooftop box, this carrier delivers.
