Sailnovo Car Rooftop Cargo Carrier Roof Bag 20 Cubic Feet - Large

Our review of the Sailnovo Car Rooftop Cargo Carrier Roof Bag finds it best suited for families and weekend travelers who need an affordable, flexible way to add storage without a hard shell box. The single biggest reason to buy is its roomy 20 cubic feet capacity that holds multiple suitcases and camping gear while folding away for storage; setup is straightforward and the included straps and hooks create a reassuringly secure fit on most cars and SUVs. It is a practical choice when you want more cargo room without the cost or permanence of a roof box.

Key Features

• Large carrying capacity: The 20 cubic feet interior fits roughly 5-7 suitcases, tents, or sleeping bags so you can free up interior space for passengers.
• Reinforced safety system: Built with 4 reinforced straps, 4 door hooks and 2 long luggage straps to keep the bag stable while driving.
• Tear-resistant material: Three layers of 1000D Oxford cloth make the bag stronger than typical 500D competitors and resist seam damage.
• Water-resistant construction: Waterproof fabric, widened zipper flaps and doubled seams reduce water ingress in light rain when zipped and the flap is secured.
• Easy installation: Comes with 6 heavy-duty tie-down straps and 4 safety hooks so the bag can be attached to crossbars, side rails or bare roofs in minutes.
• Compact storage: The soft shell design folds into an included storage bag when not in use to save garage space.

Who It's For

This rooftop bag is ideal for weekend road trippers, families with extra luggage, and campers who need a flexible, low-cost way to increase cargo capacity. Drivers with cars, SUVs, hatchbacks, crossovers and many pickups will find it fits both vehicles with roof racks and many bare roofs thanks to the tie-down straps and safety hooks.

It is not suited for vehicles with sliding doors and is not intended as a perfect waterproof vault in extreme weather; shoppers who need a fully rigid, guaranteed waterproof roof box should look elsewhere.

Pros & Cons
