Running out of trunk space does not have to mean leaving gear behind. A roof rack turns the dead space above your car into a second trunk, but the options range from 50 dollar soft bags to 500 dollar hard-shell boxes, and the wrong choice whistles at highway speed or soaks your luggage in the first rainstorm. Whether you need a proven steel basket like Best Overall, a lockable hard-shell box like Best Hard-Shell Box, a no-rails-needed soft bag like Best Budget, the biggest basket made like Best Large Basket, or a complete kit like Best Complete Kit, the right pick depends on what you carry and how often. Our top pick is the MaxxHaul basket, the 11,788-review workhorse that fits nearly everything. Here is how each pick earned its place.

This is for the occasional road-tripper whose car has a bare roof. At 53.98 dollars it costs less than one checked bag fee on some airlines, and it folds flat into a closet when the trip is over. You would regret a basket if you have no crossbars, because the basket alone is useless without them.
I love that this bag asks nothing of your car: no rails, no crossbars, no tools, just straps through the door frames and 15 cubic feet of waterproof storage. The 840D PVC with welded seams is genuinely waterproof, not water-resistant, and 8,942 reviews confirm it survives real rainstorms. Compared to the MaxxHaul basket, it is half the price and needs no rack, but it cannot carry heavy gear and offers zero theft protection. It is the right answer for soft luggage on a budget, and the wrong answer for anything you would miss if it vanished at a rest stop.
Yes if your car has no rails and you want the cheapest dry storage for a road trip. Straps on in minutes, no tools, no extra purchases. If you carry heavy or valuable gear regularly, the MaxxHaul basket or the hard-shell box is the grown-up answer.

This is for the buyer who hates piecemeal shopping. Basket for the bulky stuff, waterproof bag for the luggage, net for the odd-shaped load, all in one 139.99 dollar box. You would regret buying the basket alone if your first rainstorm sends you back to buy the bag separately at full price.
I love bundle math when it actually works: the 64x39 steel basket alone would cost you 150 dollars from most brands, and here you get the waterproof bag, cargo net, and ratchet straps in the same box for 139.99. The basket is genuinely large at 64 inches, dwarfing our overall pick, with the same 150-pound rating. Compared to the 64-inch basket at 151.96 dollars with no accessories, the WEIZE is cheaper and more complete. The trade is brand track record: 1,864 reviews is solid, but it is not the 11,788 behind the MaxxHaul.
Yes if you want to buy once and never think about roof storage again. The bundle eliminates the accessory math entirely. If you already own straps or a bag, the MaxxHaul basket alone saves 30 dollars.

This is for the family camper whose gear list grows every year. The extension takes the basket from large to enormous, swallowing the bulky items that never fit inside the car. You would regret a standard basket if you are already playing Tetris with the trunk on every trip.
I love that this basket solves the actual problem, which is volume, not weight: at 64 by 39 inches with the extension, it holds the awkward bulky gear that defeats smaller baskets. The included wind fairing is a thoughtful touch most baskets charge extra for, keeping highway noise down. At 151.96 dollars it costs only 40 more than the MaxxHaul while offering roughly 60 percent more floor area. Compared to the WEIZE kit, you get a slightly better-reviewed basket but no bag or net, so budget for weather protection. Measure twice: this much basket needs a long roof.
Yes if you regularly max out a standard basket: coolers, tents, duffels, and camp chairs all at once. Measure your roof first, because 64 inches overhangs smaller cars. For typical loads, the MaxxHaul basket is plenty and 40 dollars cheaper.

This is for the driver who wants roof storage to just work: camping trips, college move-ins, ski weekends. The universal fit means it works on the car you have now and the one you buy next. You would regret a no-name basket if rust or a failed weld ruins a trip, which is exactly what 11,788 reviews insure against.
I trust this basket because 11,788 people have already punished it with coolers, luggage, and lumber, and it holds 4.5 stars. The powder-coated steel frame shrugs off weather that would rust cheaper baskets, and the universal clamp design fits factory or aftermarket crossbars on cars, SUVs, vans, and RVs. At 109.99 dollars it undercuts the 64-inch basket by 40 dollars while covering the loads most people actually carry. The honest trade is weather protection: it is an open basket, so pair it with a waterproof bag for luggage. For bulky durable gear, nothing beats it at this price.
Yes if you want the default answer to roof cargo. It fits nearly any vehicle with crossbars, carries 150 pounds, and has more reviews than every competitor combined. If you need weatherproof lockable storage, step up to the hard-shell box; if you have no rails at all, get the soft bag.
Baskets clamp to crossbars or raised side rails. If your car has neither, soft cargo bags strap through the door frames and need no rack at all. Crossbars are the most common missing piece, and many cars accept affordable aftermarket sets.
Soft bags are made from waterproof PVC with welded seams and keep contents dry in heavy rain. Open baskets offer no weather protection on their own, which is why many are sold with waterproof bags. Hard-shell boxes are the most weatherproof option.
Yes, expect some. Open baskets are the noisiest, especially without a wind fairing; hard-shell boxes are quieter thanks to aerodynamics; soft bags sit low and make the least noise. Removing the rack between trips eliminates the noise and saves fuel.
Check your owner's manual for the roof load limit, typically 100 to 165 pounds including the rack itself. The rack's own rating, often 150 pounds, can exceed what the car roof is rated for. The car's limit always wins.
Thule's wedge-shaped basket with included wind fairing at 499.95 dollars. Superb build and quieter than most baskets, but five times the price of our overall pick for similar capacity.
See PriceAmazonThe biggest soft bag here at 23 cubic feet with double weatherproof zippers, 4.6 stars across 5,314 reviews. Lost the budget slot on price at 152.80 dollars, but it is the bag to beat for capacity.
