Rightline Auto Duffle Bag

This duffel-style cargo bag lets you carry 4.2 cu ft of gear on your vehicle's bare roof, roof rack, or cargo basket. You can also secure it to a hitch-mounted cargo carrier or simply throw it in your trunk or truck bed. It includes a removable shoulder strap that makes it easy to carry the bag away from your vehicle. The bag is constructed of waterproof material that helps to keep your gear clean and dry, and it has a large zippered opening on the top for easy loading.

Waterproof Fabric with Watertight Seams

Waterproof fabric

The rooftop cargo bag is made of PVC that's reinforced with a polyester mesh grid so it's hard to cut or tear. This durable fabric is waterproof, and it stays flexible in hot or cold temperatures so it can be folded compactly for storage. The PVC mesh is also fused together at the seams to create a watertight seal, and it's also UV protected so it won't fade.

Large, Zippered Opening

Zippered opening

A large zippered opening on top of the bag makes it easy to load and unload your cargo. The urethane-coated zipper is rust and corrosion resistant, and it's protected from the elements by a flap with a hook-and-loop fastener.

Convenient Side Pocket

Side pocket

The zippered side pocket provides convenient storage for the bag's shoulder strap or attachment straps when not in use. It's also great for storing smaller items like keys and cash. It has a urethane-coated zipper that is rust and corrosion resistant.

Versatile Mounting Options

Rightline Auto Duffle Bag on bare roof

You can mount the Rightline bag to a bare roof using the included adjustable straps with rubber-coated steel hooks. These straps adjust with integrated buckles, and the hooks firmly grip the top of each doorframe.

Rightline Auto Duffle Bag with doors closing over straps with hooks

The hooks require solid mounting points such as rain gutters, metal ledges, the outside of the weather molding, or ledges under the weather molding. Each hook has a 5/8" opening to fit over the door ledge. Your vehicle's doors should close easily over the hooks to secure them in place. The rubber coating on the hooks protects your vehicle from scratches. The attachment straps thread through D-rings on the bag for added security.

A roof pad (RL100650 - sold separately) is also available to keep the duffel bag from sliding around and to protect the top of your vehicle from scratches.

Rightline Auto Duffle Bag on cargo basket

To attach the bag to a roof rack or basket, just remove the hooks from the strap ends and use the straps to tie down the duffel bag.

Carry More Gear

Rightline Auto Duffle Bag multiple bags

You can place up to 4 Rightline duffel bags side by side on top of your vehicle, depending on the width of your roof. Get a bag for each member of the family, and everyone can grab their gear and go at the end of any journey.

Easy To Transport

Rightline Auto Duffle Bag shoulder straps

The adjustable nylon shoulder strap allows you to comfortably transport the bag to and from your vehicle. This strap can be removed and stored in the bag when not in use.

Rightline Auto Duffle Bag handles

There are also handles on each end of the bag that make it easy to lift and load.
