WORKPRO Rooftop Cargo Carrier Bag 21 cu ft Waterproof Roof Bag, 52x40x17in Rectangular with Reinforced Straps

When you need extra room for suitcases, camping gear, or sports equipment, this WORKPRO rooftop carrier offers a high-capacity, weather-resistant option that fits sedans, SUVs, wagons and many vehicles without a factory roof rack. Built from 840D PVC with double-layer protection, welded seams and reinforced straps, it balances large volume with secure attachment and easy setup so you can load up and head out quickly.

How much gear will the 21 cubic feet actually hold?

The WORKPRO bag measures roughly 52" x 40" x 17" and provides about 21 cubic feet of storage—enough for multiple suitcases or a mix of bulky outdoor items. Its rectangular shape maximizes usable space and helps stack soft bags or odd-shaped gear efficiently.

• Fits 6–8 medium suitcases or equivalent camping equipment
• Rectangular footprint simplifies packing and stacking
• Soft sides allow some compression for tighter loads

Is it really waterproof and suitable for bad weather?

The bag uses heat-sealed welds, double-stitched seams and a double-layer PVC cover to resist rain, snow and road spray. It’s designed to be highly water-resistant for normal travel conditions, but like any soft carrier, it should be inspected after heavy storms or abrasive contact to maintain performance.

• 840D PVC outer material with double-layer cover
• Welded and double-stitched seams for improved seal
• Reflective strips increase visibility at night

How does installation and security work on different cars?

Installation takes minutes using six door hooks and ten reinforced adjustable straps to secure the bag to most vehicle roofs, with no specialized tools required. An included anti-slip mat reduces movement and prevents scratches; follow the manual to avoid attaching straps to side bars incorrectly.

• Six quick door hooks for tool-free mounting
• Ten reinforced adjustable straps for balanced hold
• Anti-slip mat included to prevent shifting and protect paint

Will using this bag affect fuel economy or driving noise?

The aerodynamic profile was built to reduce drag compared with blocky loads, helping lower wind noise and fuel penalty versus untamed rooftop luggage. Expect some additional noise and consumption compared to an empty roof, but the streamlined shape minimizes those penalties.

• Aerodynamic shape to cut wind resistance
• Low-profile design for reduced road noise
• Secure straps keep load stable at highway speeds

Who is this for: The WORKPRO rooftop cargo carrier is ideal for families and outdoor enthusiasts who need flexible, high-volume roof storage without the expense or permanence of a hard shell. Choose this bag if you want a weather-resistant, easy-to-install roof solution for road trips, camping weekends, sports gear transport or anytime interior space is limited.

What’s included: 1 WORKPRO car rooftop carrier bag, 6 safety hooks, 2 reinforced straps, 1 anti-slip mat (storage bag), and a user manual. Note: this is a soft rooftop carrier — avoid fastening front/rear straps to side bars to prevent stress and potential damage.
