Sailnovo Rooftop Cargo Carrier 20 cuft Waterproof Roof Bag - Travel

In this review the Sailnovo rooftop cargo carrier proves itself as a straightforward, high-capacity solution for families and road trippers who need more space without a roof rack. The single biggest reason to buy is the carrier's combination of a true 20 cuft capacity and weather-resistant construction, which makes it ideal for multi-day trips where suitcases, tents, and sleeping bags would otherwise crowd the cabin. Installation is simple and fast using straps and door hooks, and the carrier folds into a storage bag when not in use, so it does not permanently affect vehicle fuel economy or garage space.

Key Features

• 20 cuft capacity: Large 51' x 39' x 17' interior fits luggage for four to seven people, reducing interior clutter on long trips.
• Waterproof and tearproof materials: Oxford fabric with a 1000D PVC lining and a 6' extended waterproof curtain help keep gear dry in rain and snow.
• Universal installation: Includes 6 reinforced straps, 2 long adjustable straps and 6 safety door hooks so the bag mounts to most cars with or without roof racks in minutes.
• Anti-slip mat and reinforced straps: Non-slip mat and double-reinforced back strap seams add stability and reduce shifting and noise on highways.
• Aerodynamic arch shape: Curved design reduces wind resistance and noise compared with boxy carriers, helping fuel efficiency and longevity.
• Complete accessory kit: The package includes a storage bag, non-slip mat, door hooks, tie-down straps and an instruction manual for a ready-to-use setup.

Who It's For

The Sailnovo roof bag is best for families, campers, and anyone taking long road trips who needs reliable, extra cargo space without installing a permanent rack. It suits people who want a foldable, stowable option that stays secure on the roof and protects gear from typical wet weather.

Those who should look elsewhere include owners of vehicles with sliding side doors (the door hooks are not compatible) and users who need a rigid, lockable rooftop trunk for repeated daily loading and unloading; a hard-shell carrier offers more theft resistance and a permanently mounted roof rack may be better for constant heavy use.

Pros & Cons

Pros

• Spacious 20 cuft volume easily accommodates multiple suitcases and camping gear.
• Robust waterproof layers and a 6' extended curtain protect contents in rain and snow.
• Quick universal installation with straps, door hooks and an anti-slip mat reduces setup time and movement while driving.
• Folds into a storage bag to save space when not in use.

Cons

• Some customers report occasional breakage of small clips under extreme stress, so heavy repeated use may wear hardware faster than a hard case.
• In very heavy or prolonged downpours it is wise to add dry bags inside as extra protection against rare leakage.

Our Verdict

Frequently Asked Questions

Will this fit my car without a roof rack?
Yes, the bag is designed to mount to most vehicles without a roof rack using the supplied straps and door hooks, though sliding doors are not compatible.

Is the carrier fully waterproof?
The carrier uses Oxford fabric with a 1000D PVC lining and an extended waterproof curtain to resist rain and snow, but in extreme downpours additional dry bags for valuables are recommended.

Does it reduce fuel efficiency?
The arched aerodynamic shape lowers wind resistance compared with a square bag, so fuel impact is minimized though some effect is inevitable with roof cargo.
