Trunk space runs out fast on a family road trip, a camping weekend, or a move across town. A roof storage solution turns your car’s unused rooftop into serious cargo room without buying a bigger vehicle. This roundup covers eight options that fit nearly any car, SUV, or van, with or without factory crossbars, so you can match one to how you actually travel.
The Picks In Brief
MaxxHaul Steel Roof Rack Cargo Basket 46″ x 36″ (70115)
BAGMATE Car Rooftop Cargo Carrier Bag, 19 Cubic Ft
Asinking Car Rooftop Cargo Carrier Bag, 15 Cubic Feet 840D
BAGMATE 23 Cubic Feet Roof Bag, Waterproof Rooftop Carrier
Sailnovo Aerodynamic Rooftop Cargo Carrier Bag, 20 Cu Ft
Asinking Car Rooftop Cargo Carrier Bag, 20 Cubic Feet Non-Rip
Asinking Car Rooftop Cargo Carrier Bag, 21 Cubic Feet
Sailnovo Rooftop Cargo Carrier Bag, 21 Cubic Soft-Shell
Meet The Standout Selections
Every soft bag in this list folds flat when empty, but the MaxxHaul 70115 is the opposite animal: an open steel basket measuring 46 by 36 inches with 4.5-inch side walls. That rigid frame means you can strap down firewood, coolers, jerry cans, or a muddy tent that would wreck fabric. The black powder-coated finish resists corrosion through wet seasons.
It mounts to vehicles already fitted with crossbars, so campers and van owners with existing racks get the most from it. One honest note: the open design exposes contents to rain and road dust, so gear needs its own covers or bags.
Useful Highlights
- Heavy-duty steel construction shrugs off sharp-edged cargo that would puncture a soft carrier
- The 46″ x 36″ footprint swallows bulky items like coolers and stacked bins
- Powder-coated finish helps the frame stand up to rain and road salt over time
- Universal mounting suits cars, SUVs, vans, and RVs with crossbars
Things To Consider
- An open basket leaves cargo exposed to weather, unlike the sealed bags further down this list
- You will need crossbars already installed, plus periodic checks that bolts stay tight after rough roads
Key Specs
Built With In Mind
Campers and property owners who regularly haul dirty, sharp, or irregularly shaped gear on a vehicle with crossbars.
A Better Fit Elsewhere
Drivers without crossbars who want weather-sealed luggage space should look at the BAGMATE 23 Cubic Feet Roof Bag instead.
Where the MaxxHaul basket demands crossbars, this BAGMATE bag works either way, strapping to a rack or anchoring through door hooks. Nineteen cubic feet translates to roughly four or five medium duffels, which covers a long weekend for two adults or a school-run overflow situation. The included anti-slip mat keeps the bag from wandering on painted roofs.
Reinforced zippers and buckles are the details worth checking here, since those are the failure points owners commonly report on cheaper bags. For occasional travelers rather than full-time road warriors, this hits a comfortable middle ground.
A Few Strong Suits
- Installs with or without a roof rack, opening it up to sedans and hatchbacks
- Nineteen cubic feet holds several suitcases plus soft gear
- Anti-slip mat protects paint and stops shifting mid-drive
- Reinforced zipper and buckle points resist the wear that kills budget bags
Small Caveats
- Four door hooks mean fewer anchor points than some rivals offer on longer trips
- Soft-shell bags need drying before storage to prevent mildew, a chore after rainy drives
Who It Suits Best
Occasional family travelers in rack-less sedans or small SUVs who want dependable extra space without permanent hardware.
Where A Sibling Pick Shines
Packers wanting more anchor points and a lock should step up to the Asinking 21 Cubic Feet model reviewed later.
Denier ratings confuse people, so here is the short version: 840D describes fabric thread thickness, and higher numbers generally mean tougher material. At 840D PVC with triple-reinforced welded seams, this smaller Asinking punches above its size on durability. Fifteen cubic feet is the modest capacity here, but that lower profile also means less wind drag and easier garage clearance.
The accessory list is where it earns attention: six door hooks, two spare straps, a luggage lock, and a storage bag all ship together. Compare that to the BAGMATE 19 cubic feet above, which trades some of that kit for extra volume.
Reasons It Performs
- 840D abrasion-resistant PVC stands up to rough handling season after season
- Welded seams are far harder to tear than stitched ones under load
- Six door hooks spread anchoring force across more contact points
- Luggage lock adds a deterrent at rest stops
Points To Note
- Fifteen cubic feet fills quickly for families of four or more
- The widened zipper flap system takes slightly longer to open and close during packing

Made For
Solo travelers and couples driving compact cars who prioritize build toughness over maximum volume.
Swap It Out When
Larger households should pick the BAGMATE 23 Cubic Feet Roof Bag, which nearly doubles the packing room.
This is the volume leader of the BAGMATE pair, sized around eight medium suitcases according to the manufacturer. Twenty-three cubic feet changes what a road trip looks like: strollers, coolers, and camping duffels all ride up top while passengers keep legroom. The military-grade 840D PVC shell and protective mat mirror the construction approach of the smaller Asinking, but scaled up.
Stability testing at highway speeds is the claim that matters most for interstate drivers, since a shifting bag is both noisy and unsafe. In our view, this is the pick for the once-a-year mega trip rather than weekly errands.
Points In Its Favor
- Twenty-three cubic feet accommodates roughly eight medium suitcases
- Highway-speed stability engineering targets wobble and shift
- Protective mat shields paint from scuffs during transit
- Storage bag included for off-season garage organization
Worth Noting
- A fully loaded bag this size raises the vehicle’s center of gravity, so cornering feels different until you adjust
- Folding it back into the storage bag after a trip takes patience
Quick Facts
Right Fit For
Families of four to six heading on multi-day vacations who need every suitcase off the cabin floor.
Another Choice May Suit
Weekend-only packers will find the 19 cubic feet BAGMATE easier to handle and store between trips.
Shape is the story here. At 51 inches long, 39 wide, and just 17 tall, this Sailnovo sits flatter against the roofline than boxier rivals, which trims wind drag and the low hum that makes long drives tiring. You may find the difference noticeable on sustained interstate stretches compared with taller bags like the BAGMATE 23.
Twenty cubic feet still fits luggage for four to six people, including tents and sleeping bags, so the slim profile costs little practical space. Reinforced straps and the anti-slip mat handle anchoring duties.
Advantages To Know
- Low 17-inch height reduces drag and wind noise at speed
- Twenty cubic feet serves groups of four to six
- Reinforced straps plus anti-slip mat limit shifting
- Flat profile helps with parking garages and drive-through clearances
Less Ideal Details
- The wide footprint may overhang narrower sedan roofs, so measure first
- Owners commonly report needing to re-tension straps after the first hour of driving
Whose Shelf It Belongs On
Commuters and frequent interstate drivers who hate wind roar but still want real cargo volume.
Reach For A Different Pick When
Rain-soaked climates favor the Sailnovo 21 Cubic Soft-Shell below, whose sealed seams target heavy downpours specifically.
Asinking positions this 20-cubic-foot version as its upgraded flagship, layering security features onto the same waterproof formula as the 15-cubic-foot model earlier in the list. The non-slip mat, luggage lock, four door hooks, and storage bag arrive in the box, so nothing else goes on the shopping list. Downpour protection is the headline claim, aimed at drivers caught in summer storms on the interstate.
The trade-off against the slimmer Sailnovo aerodynamic bag is height: more volume means a taller stack and a bit more wind presence. Detail-oriented packers who value locks and layered closures will appreciate the extras.
Useful Touches
- Waterproofing engineered for sustained heavy rain, not just light drizzle
- Luggage lock secures the zipper at stops
- Non-slip mat doubles as paint protection
- Complete accessory bundle removes guesswork from setup
Details To Watch
- Four hooks provide fewer anchor points than the 21-cubic-foot Asinking’s six
- Layered waterproofing adds bulk when folding the empty bag away
Best Suited To
Storm-belt drivers and security-conscious travelers who want locking storage without stepping up in size.
Look Elsewhere When
Maximum anchoring matters more than anything else, and the Asinking 21 Cubic Feet model’s ten straps do that job better.
Ten reinforced straps set this Asinking apart from every other soft bag here. More anchor points spread the load across the roof and doors, which is exactly what you want on washboard back roads or gusty plains highways. The 900D PVC tarpaulin shell uses high-frequency welded seams, a process that fuses material edges into one piece rather than stitching them.
At 21 cubic feet it slots between the BAGMATE 23 and the smaller Asinking options, and the six-hook, lock, and mat bundle matches the family’s usual completeness. Long-distance road-trippers get the strongest anchoring package in this roundup.
The Case For It
- Ten reinforced straps deliver the most secure attachment points here
- 900D PVC tarpaulin with welded seams resists tears and leaks
- Six door hooks plus anti-slip mat stabilize the load fully
- Twenty-one cubic feet balances volume against roof profile
Trade Offs To Consider
- Routing ten straps correctly adds a few minutes to installation versus four-hook designs
- Extra straps need coiling and storing inside the bag after each use

Who Will Love This
Road-trippers covering mixed terrain and long distances who refuse to compromise on attachment security.
Not Your Match When
Speed-focused commuters chasing minimal wind noise will prefer the Sailnovo Aerodynamic 20 Cu Ft bag’s flatter shape.
Sailnovo closes the list with its largest soft bag, pairing 1000D PVC coating with sealed seams and extended zipper flaps built specifically for heavy rain. Where the brand’s aerodynamic 20-cubic-foot model chases a slim shape, this 21-cubic-foot version prioritizes weather sealing and abrasion resistance for camping gear that sees real abuse.
The streamlined silhouette still aims to cut drag relative to conventional boxes, which keeps highway manners civil. Wet-climate travelers, think Pacific Northwest winters or Gulf Coast summers, get the most targeted protection in this lineup.
Bright Spots
- Sealed seams plus extended zipper flaps target heavy-rain performance
- 1000D PVC coating withstands abrasion from rough gear
- Aerodynamic form reduces drag compared with hard boxes
- Twenty-one cubic feet swallows camping equipment for a family
Room For Improvement
- Soft shells compress under stacking weight, so fragile items belong inside hard cases
- Thorough drying before storage prevents odor buildup, a common soft-bag complaint
Technical Reference
The Right Fit
Campers and coastal residents who face regular heavy rain and want their bedding and electronics arriving dry.
Consider Something Else When
Drivers hauling sharp or dirty gear should choose the MaxxHaul steel basket, whose open frame tolerates abuse fabric cannot.
What Matters Most Before Choosing Car Roof Storages
Match The Mount To Your Vehicle
Crossbars change everything. Steel baskets like the MaxxHaul require them, while every soft bag here works with or without a rack using door hooks. Check your roof type first, then filter the shortlist accordingly.
Capacity Versus Clearance
Volume sounds purely good until you meet a parking garage. Bags over 20 cubic feet sit taller and wider, and a loaded roof raises your vehicle’s center of gravity. Weekend couples rarely need more than 15 to 19 cubic feet; families of five should start at 21.
Weather Sealing Levels
Waterproof claims vary widely. Welded seams beat stitched ones, extended zipper flaps matter in sustained rain, and an anti-slip mat protects both paint and load stability. Prioritize seam construction over marketing labels.
Anchoring And Security
Strap count directly affects stability at highway speeds. Six hooks outperform four, ten straps outperform six, and a luggage lock deters opportunistic theft at rest stops.
Key Considerations Across These Picks
Traps First Timers Fall Into
The classic error is ordering a bag too large for the actual roof, then discovering overhang at 65 mph. Another common slip: skipping the anti-slip mat and watching paint suffer. Measure your roof and read the strap routing guide before the first trip.
What Separates Premium From Basic
Higher-tier bags spend money where failures happen: denier rating, welded seams, strap reinforcement, and locking zippers. Paying up pays off for annual long-haul travelers; occasional users get genuine value from simpler kits.
Closing Thoughts
Roof storage comes down to honesty about your trips. Haul messy gear on crossbars, and the MaxxHaul basket earns its spot. Chase quiet highways, and the Sailnovo aerodynamic bag fits. Big family vacations point to the BAGMATE 23 or the strap-heavy Asinking 21. Whichever direction you lean, measure your roof, pack smart, and enjoy the extra room.
