Sailnovo Rooftop Cargo Carrier Roof Bag (21 Cubic Feet) with anti-slip mat, security lock and 6 door hooks
Product description
If you’re trying to pack a road trip without turning the boot into a Tetris challenge, a soft roof bag is a sensible workaround. The Sailnovo Rooftop Cargo Carrier Roof Bag is built for that “use the roof, keep the inside livable” idea, and it leans on a few practical add-ons like an anti-slip mat, a security lock and multiple door hooks.
That said, it’s not going to behave like a rigid hard-shell carrier in every situation. It’s soft, it folds when stored, and it’s designed around being strapped down securely—so it works best when you pack thoughtfully and expect a bit of give rather than a rigid shell.
Key takeaways
On paper, this roof bag targets family trips, camping weekends and general overflow packing. With a stated storage capacity of 21 cubic feet and dimensions of 51 inches (length) x 39 inches (width) x 17 inches (height), it’s aiming for the “5–7 suitcases plus outdoor extras” sort of haul mentioned by the manufacturer.

Where it stands out is the combination of tougher materials and safety-focused features. It uses wear-resistant and cold-resistant PVC, includes a Velcro cover designed to reflect all directions for better visibility at night, and claims waterproofing help via “10 waterproof stickers”. Plus, the package includes practical items (anti-slip mat, safety lock, and 6 door hooks), so you’re not forced to hunt around for accessories right away.
One limitation worth noting: because it’s a soft bag, its real-world stability depends quite a lot on how evenly you distribute weight and how tight you tension the straps. If your load is lumpy or top-heavy, you may find you need extra care compared with more structured roof carriers.
What to know before you buy


This is a rooftop cargo carrier roof bag, intended for cars with or without rack. The listing also mentions that the bag can be folded into storage bags when not in use—handy if you don’t have loads of space at home.

In practical terms, the bag is best considered for “bulk but manageable” items: travel luggage, sleeping bags, camping tents, and similar soft or compressible gear. The size suggests you’re not really buying it for small daily storage, you’re buying it for trips where you want to move bulky items up top and free up inside space.
A small detail that can make a difference is the organiser element included (drawstring roof bag organiser), plus a door hook storage bag. These sound minor, but in use, they’re often what keep things from becoming a strap-and-hook mess at the roadside.

What stands out in everyday use
The anti-slip mat and non-slip leather door hooks are the kind of “quiet” improvements that matter once you’re actually loading the car. Instead of relying purely on the bag material, the setup is meant to reduce sliding where the roof contact happens.


The reflective Velcro cover is another thoughtful touch. Road trips involve changes in light—arrivals after dark, early motorway driving, that sort of thing. A reflective cover designed to reflect in all directions can help you feel a bit more visible.
As for the waterproof angle, the listing is phrased as avoiding water leaks via 10 waterproof stickers. That’s not a guarantee of “submersion-proof” performance, but it does suggest Sailnovo has tried to address seams and vulnerable areas.

If you picture using it: lay the bag flat, arrange bulk items evenly (for example, stack suitcases and then place sleeping bags around them rather than piling everything into one corner), tension it so it doesn’t sag, and then make use of the door hook storage bag so your hooks stay together until the next trip.
Pros
- Large stated capacity of 21 cubic feet for travel and camping overflow
- Cold-resistant, wear-resistant PVC material with foldable storage when not in use
- Reflective Velcro cover designed to reflect all directions for night visibility
- Includes anti-slip mat and a security lock, plus 6 door hooks
- Waterproofing support via “10 waterproof stickers”
- Comes with organiser and storage for the door hooks, not just the bag itself
Is it worth it?

Buying this makes sense if you need extra roof space for road trips and camping and you’re comfortable with a soft carrier that relies on correct loading and securing. It’s also appealing if you want the package to include key extras (anti-slip mat, security lock, and 6 door hooks) so you can get going without additional shopping.


You may want to skip it if you’re after the more predictable rigidity of a hard-shell system, or if your trips involve highly irregular, awkward loads that are hard to distribute evenly. Since the bag’s stability will depend on how it’s strapped down and how balanced your items are, it may not suit everyone.
