What stands out
- 20 cubic feet of storage space in a 52 x 40 x 12-18.5 inch bag
- 900D PVC tarpaulin shell with triple-reinforced seams for 100% waterproof protection
- Fits vehicles with or without roof racks, rails, or sunroofs

Who it fits
Good fit for
This carrier suits drivers who need flexible storage without installing permanent roof racks. It works well for small, medium, or large cars. The waterproof 900D PVC shell protects luggage from rain and dust. You will appreciate the easy installation using metal ring straps if your car lacks crossbars. The 20 cubic feet capacity handles road trip essentials. It is ideal for those who want to avoid the bulk of hard boxes while keeping gear dry and secure.
Who should skip it
Skip this option if you need maximum security against theft. While it includes a lock, a soft bag is easier to cut through than a hard shell. You might also look elsewhere if you require a rigid structure for heavy, sharp items that could puncture the PVC tarpaulin. The soft sides offer less impact protection than aluminum or ABS plastic boxes. If you frequently drive on rough terrain with heavy loads, a rigid carrier provides better stability and durability for your specific needs.
Verdict: This roof bag provides practical, waterproof storage for vehicles without racks. It is a solid choice for travelers needing flexible capacity without permanent modifications.
Key specs explained for this roof bag
Capacity: 20 cu ft
This volume tells you how much gear fits inside. Twenty cubic feet is enough for several large duffel bags or a few suitcases. You can pack more than you might expect for a soft bag. Compare this to hard boxes, which often offer similar space but cost more. This capacity suits families needing extra room for road trips without buying a bulky carrier.
Dimensions: 52 x 40 x 12-18.5 in
These measurements define the bag's footprint and height range. The length and width fit most standard roof racks. The height adjusts from 12 to 18.5 inches depending on how much you pack. A lower profile helps with aerodynamics. You should measure your rack spacing to ensure the 40-inch width does not overhang your vehicle sides.
Shell Type: 900D PVC tarpaulin
This fabric choice determines durability and water protection. Nine-hundred denier PVC is thick and resistant to tears. It stands up to rough handling better than thin nylon. The material blocks moisture effectively. You do not need a separate rain cover. This construction is ideal for buyers who prioritize long-lasting gear that resists wear and weather exposure.
Installation: Metal ring strap design
This mechanism secures the bag to your roof rack. Metal rings provide a sturdy anchor point for the straps. This design simplifies the setup process compared to complex buckle systems. You can attach it to cars with or without side rails. The straightforward installation means you spend less time securing the load and more time on your journey.
Water Resistance: 100% waterproof
This claim indicates the bag keeps contents dry in heavy rain. The design uses triple-reinforced seams and a double-flap zipper. These features prevent water from seeping in through stitch holes or gaps. You can trust this bag for wet climates or unexpected storms. It offers protection similar to hard boxes but with the flexibility of a soft carrier.
Design and build details
The listing describes a soft-sided carrier made from 900D PVC tarpaulin. This material choice suggests durability against tears and peeling. According to the listing, the construction includes triple-reinforced seams with no exposed stitching. This design aims to prevent water from seeping in through needle holes. A double flap covers the zipper, secured by Velcro, which adds a layer of protection for your gear. The straps are noted as water-repellent, and the metal ring strap design simplifies installation on vehicles with or without side rails.
The bag measures 52 inches long and 40 inches wide. The height adjusts from 12 to 18.5 inches, allowing you to compress the load when space is tight. This flexibility helps keep the center of gravity lower. The listing claims the front is lower than the back to reduce wind noise and improve fuel efficiency. Thick pads on the door hooks protect your car’s paint, while a rubber mat safeguards the roof surface. These features indicate a design focused on protecting both your cargo and your vehicle’s finish.
The carrier folds flat for storage when not in use. This foldable nature means it takes up minimal space in your garage or trunk. The listing states the material resists cold, heat, UV rays, and dust. This resistance ensures the bag remains functional across different seasons. The lockable feature adds security for your luggage. The overall build prioritizes practical storage that fits various vehicle types, from small cars to large SUVs.
Setup and everyday use guide
Installation relies on a metal ring strap design that secures the carrier to your vehicle. This system works whether your car has side rails, crossbars, or no roof rack at all. The listing notes that the bag fits any size car, including those with sunroofs or moonroofs. You place the carrier on the roof, then tighten the straps. Thick pads on the door hooks protect your door frame paint, while a rubber mat safeguards the roof surface. This setup ensures the carrier stays secure even at highway speeds or on rough terrain.
Daily use begins with loading your gear. The 20 cubic feet of space fits several large duffel bags or suitcases. The 900D PVC tarpaulin shell is 100% waterproof. Triple-reinforced seams and a double-flap zipper with velcro keep contents dry. The zipper has no gap, and the straps are water-repellent. You should install the bag with the logo facing front for optimal water shedding.
The shape is lower at the front and higher at the back. This design aims to reduce wind noise and improve fuel efficiency. The carrier measures 52 inches long and 40 inches wide. Height ranges from 12 to 18.5 inches depending on load. When not in use, the soft material folds flat. This allows you to store it without taking up much space. The lockable feature adds security for your luggage while parked. The material resists cold, heat, UV rays, and dust, ensuring it remains durable through repeated use.
Before You Buy This Roof Bag
You need to verify your vehicle’s roof weight limit before loading. The listing states the straps can support up to 3100 lbs, but your car’s roof rails or bare roof may have a much lower maximum capacity. Exceeding your vehicle’s limit is unsafe. You should also check the height of your roof rack. The bag measures 12 to 18.5 inches tall, which adds significant height to your vehicle. Ensure you have enough clearance for garage doors and low bridges. Since this is a soft-sided carrier, you must pack items carefully to avoid sharp edges that could puncture the 900D PVC material. Unlike hard shell boxes, this option is foldable for storage when not in use. It sits alongside rigid carriers as a flexible, lower-profile alternative for those without permanent roof racks. Always keep the included rubber mat on your roof to protect the paint finish from scratches during installation and removal.
Check before you buy
- Check your vehicle's maximum roof load capacity.
- Measure your roof rack height and vehicle clearance.
- Ensure your car fits the 52 x 40 inch footprint.
- Verify the bag fits with or without existing rails.
