If you’re after one of the 10 best rooftop cargo boxes that carry your skis in style, the goal is simple: keep your boards protected, secure, and easy to load. Before buying, check interior length against your longest ski, roof-bar compatibility, and how easily the lid opens, locks, and loads from both sides—especially if you’re hauling gear for the whole family.
We selected contenders using manufacturer specs, real-world feedback, brand reputation, and how well each box mounts and locks on the roof.
Below you’ll find the best supplies, helpful fit notes, and what’s genuinely worth buying, so you can head to the hill without second-guessing your setup.
How We Tested
We compared interior length, cargo capacity, dual side opening, roof bar compatibility, lock systems, and price.
Each pick matched corresponding, appropriate specs for skis and ski pairs, not subjective impressions.
We checked interior length against longest skis and cargo capacity for six to eight ski pairs or three to four.
We favored dual side opening lids for snowbank access and roof bar compatibility for secure, tool free clamps.
Our final list weighed lock systems that secure the lid before key removal and price against those specs.
This buyer intent comparison balanced easy loading near snowbanks with confident roof bar mounting.

More Details on Our Top Picks
INNO Wedge 660 Black Roof Rack Cargo Box
The INNO Wedge 660 Black Roof Rack Cargo Box works best for skiers and snowboarders who want a quiet ride on long highway drives and quick mounting for weekend trips. Its clear strength is a low profile hard shell that cuts wind noise while still holding 4 snowboards or 6 to 8 skis.
One honest drawback is that the 11 cubic foot space can feel tight for a big family or a long trip with bulky gear, so pack light or compare with larger boxes. This box differs from many cargo boxes because it uses the SPM Injection Process for a stiffer shell with even thickness, while vacuum formed shells can flex more.
You get dual side opening for loading from either side, which helps when you park tight against a snowbank. The Memory Mount system lets you install it without tools after the first setup, so you can pop it on and off in minutes.
The advanced lock will not let you remove the key until the box is fully secured, so you will not drive off with it ajar. It fits aero and square bars, so it works with most roof rack setups.
For a quiet, sturdy cargo box that is easy to mount, the Wedge 660 is a strong pick before the next storm hits. If you need maximum space for a large group, look at a bigger box; if you want a calm ride and simple loading, choose the Wedge 660.
- Storage Capacity:11 cu ft
- Ski/Snowboard Capacity:4 snowboards or 6-8 skis
- Opening Type:Dual-side opening
- Crossbar Compatibility:Aero and square bars
- Locking System:Advanced safety lock (key removal only when locked)
- Construction Material:SPM Injection Process hard shell
- Additional Feature:Made in Japan
- Additional Feature:50% stronger than vacuum-formed
- Additional Feature:Memory Mount tool-free install
INNO Wedge Plus Rooftop Cargo Box 13 cu ft
The INNO Wedge Plus is best for weekend skiers and small ski groups who want a mid size value pick with aerodynamic roof storage and a lower price than premium brands. It gives you 13 cubic feet of space, enough for six to eight pairs of skis or four to six snowboards, depending on bindings.
Its clearest strength is the dual side opening, which makes loading and unloading easier in tight garages and busy ski resort parking lots. The safety lock only lets you remove the key when the lid is fully secured, so you get extra peace of mind before you drive.
The main limitation is capacity: 13 cubic feet leaves little spare room for extra luggage, helmets, or very long skis on trips with several people. It differs from larger cargo boxes and premium name brands by focusing on easy mounting, a lower price, and simple daily use for smaller ski loads.
It mounts to aero, square, or round roof bars without much fuss, and the three layer ABS top is made in Japan for long term durability. Choose this ski cargo box when you want a practical roof box for weekend ski trips and you can pack around its modest capacity.
- Storage Capacity:13 cu ft
- Ski/Snowboard Capacity:4-6 snowboards or 6-8 skis
- Opening Type:Dual-side opening
- Crossbar Compatibility:Aero, square, round, most factory crossbars
- Locking System:Safety lock system (key removal only when locked)
- Construction Material:3-layer ABS top, SPM injection base
- Additional Feature:3-layer ABS top material
- Additional Feature:Made in Japan
- Additional Feature:Exterior dimensions 80.75 inches
INNO ROOF Gear Case BRM715MBK Matte Black
This INNO ROOF Gear Case BRM715MBK is a compact parking pick for urban skiers and snowboarders who park in tight garages. It fits best on small SUVs such as a Jimny, where every centimeter of garage clearance counts.
At 8 cubic feet, it holds 3 to 4 skis or 2 to 3 snowboards, and its low profile keeps a Jimny under 2.1 meters. That clearance is the clear strength of this roof box for winter sports trips in the city.
The hard shell has a matte black finish that resists scrapes, and the side handle lets you open the gear case with one hand. The symmetrical ends also let you change which side opens, which helps when you load a ski carrier from the curb or the driver side.
The Memory Mount System fits aero bars or square bars without tools, and the key can come out only when the box is locked. These details make the cargo carrier easy to live with on a daily basis.
The honest drawback is space: this is a small roof box, so limited space means you pack skis, snowboards, and small gear only. It also carries a pricey sticker, even though it is Made in Japan and feels precise.
Compared with larger roof boxes, this INNO model gives up cargo volume to keep a lower shape for parking garage clearance. If garage clearance tops your list for a ski trip, this compact parking pick is a good match; if you need room for a full wardrobe, choose a bigger cargo box.
- Storage Capacity:8 cu ft
- Ski/Snowboard Capacity:2-3 snowboards or 3-4 skis
- Opening Type:Single-side opening (front/rear symmetrical for left or right)
- Crossbar Compatibility:Aero, square, round, most factory crossbars
- Locking System:Safety lock system (key removal only when locked)
- Construction Material:Rugged hard shell
- Additional Feature:Fits multi-story parking
- Additional Feature:Front/rear symmetrical design
- Additional Feature:One-hand grip opening
Thule Pulse 2 M Roof-Mounted Cargo Box 14 Cubic Ft
Thule Pulse 2 M is our editor’s choice for shoppers who need a sleek, no fuss roof box for modern crossover SUVs and ski trips. It gives you 14 cubic feet, or 400 liters, for skis, snowboards, poles, and luggage, and it carries up to 75 kg.
Its clear strength is easy access from both sides, so you can grab gear without walking around the car. The forward mount also keeps your trunk fully accessible when you load up for a ski weekend.
The ASA ABS plastic resists sun, scratches, and weather, and the clamp needs no tools: it clicks at the right torque so you do not have to guess. It locks securely, which helps you avoid gripping the wheel with worry on the highway.
One honest limitation is space: 14 cubic feet can feel tight for a large family or for long trips with wide skis and lots of luggage, and the 75 kg cap sets a firm ceiling. Compared with larger roof boxes, this Thule model differs by keeping a middle size footprint that fits your roof line without taking over, and it is simpler to mount than bulky expedition boxes.
- Storage Capacity:14 cu ft (400L)
- Ski/Snowboard Capacity:Not specified (75 kg load capacity)
- Opening Type:Dual-side opening
- Crossbar Compatibility:Universal (tool-free system)
- Locking System:Confirms closure for peace of mind
- Construction Material:ASA-ABS plastic

SportRack Sidekick Cargo Box
If you drive a sedan or small crossover, the SportRack Sidekick is a compact rooftop cargo box made for light loads and tight roof space. Its clear strength is the 8 cubic feet of room for camping gear or golf clubs while leaving rack space for extras.
The Sidekick fits where bigger boxes won’t, so compare it with larger cargo boxes if you need room for long skis or a family ski trip. You get sturdy U bolts that clamp onto square bars, round bars, or most factory racks, and the passenger side opening makes curbside loading easier.
It locks to help protect your gear from thieves, which is a useful feature for weekend ski trips and daily errands. The honest limitation is limited ski capacity: this box is a solid affordable pick for light loads, but it cannot haul skis for the whole family.
For buyers who want a budget cargo box for small vehicles, the Sidekick is a practical choice. It differs from larger roof boxes by keeping a smaller footprint and leaving more rack space, so it matches simple gear and short ski trips.
- Storage Capacity:8 cu ft
- Ski/Snowboard Capacity:Not specified (75 lb load capacity)
- Opening Type:Passenger-side opening
- Crossbar Compatibility:Square, round, most factory racks
- Locking System:Lock included
- Construction Material:Not specified

- Additional Feature:Passenger-side opening
INNO ROOF Box 320 Matte Black Cargo Carrier
The INNO ROOF Box 320 is best for drivers who want a small roof cargo box for ski trips and easy loading at the car. It gives you a compact, square design that weighs just 37 lbs, yet it holds 9 cubic feet of gear.
Open it from either side to reach up to 4 snowboards or 6 to 8 pairs of skis inside a matte black shell. Its clearest strength is the dual side opening plus an integrated lock system that will not release the key until the box is fully locked, a useful detail for forgetful drivers.
The honest drawback is capacity: this compact roof box will not fit a large family load or gear beyond the stated 4 snowboards or 6 to 8 pairs of skis. It differs from larger roof boxes by saving weight and garage space, and it differs from soft cargo bags by adding a hard shell, locks, and access from both sides.
Universal mounting fits aero, square, round, or factory bars, and the Memory Mount System remembers its spot for easy install. The tough two layer ABS top and SPM injection base help it feel solid without the bulk.
For quick trips and sleek looks, choose this roof cargo box for carrying skis and snowboards. It is made in Japan and suits drivers who want secure ski storage without wrestling a giant tote bag up a ladder.
- Storage Capacity:9 cu ft
- Ski/Snowboard Capacity:4 snowboards or 6-8 skis
- Opening Type:Dual-side opening
- Crossbar Compatibility:Aero, square, round, most factory crossbars
- Locking System:Integrated safety lock (key removal only when locked)

GarveeTech Rooftop Cargo Box Carrier Dual-Side Opening
If you are packing a family of five for a ski weekend, a snowboard trip, or a long road trip, the GarveeTech Rooftop Cargo Box Carrier is best for that job. It gives you a rigid ABS shell that is fully waterproof, so slush, rain, and road spray stay outside the box.
This waterproof rooftop cargo carrier comes in 12 or 14 cubic feet (340 to 390 liters, about four to five big suitcases). You can fit skis, ski boots, and a cooler inside, and the max load is 165 pounds, so keep the weight under that limit.
Its clear strength is the dual side opening: you can load from either side when you reach the mountain. The main limitation is roof rack fit, so measure your crossbars before you buy and confirm the carrier works with your SUV or wagon.
Compared with soft roof bags, the ABS shell holds its shape and protects gear from wet weather. The aerodynamic shape helps cut wind noise and fuel burn on highway drives.
It fits most roof racks, but always double check your rack and the box mounting points. The package includes two keys and straps, which helps with quick access and securing your load.
A one year warranty covers the box, and support answers within a day. This cargo carrier is solid value for the price if you need extra space for ski gear and family luggage.
Measure your roof rack first, then load up for the mountain. Keep one side locked while you load, and keep the keys handy so the dual side opening works smoothly.
- Storage Capacity:12 or 14 cu ft
- Ski/Snowboard Capacity:Not specified (165 lb max capacity)
- Opening Type:Dual-side opening
- Crossbar Compatibility:Universal fit for vehicles with roof racks
- Locking System:2 keys included
- Construction Material:ABS hard-shell

DNA Motoring Rooftop Cargo Box (Glossy Black)
This DNA Motoring rooftop cargo box is best for weekend skiers and road trippers who need extra gear space on their cross bars and want a fast setup. It mounts with no tools required, so you can add 11 cubic feet of cargo space in minutes and get moving on your ski trip.
The box holds up to 110 pounds when you balance the load evenly, and its side lid stays open on its own while you load skis or snowboards. A clear strength is the rugged ABS plastic shell, which handles weather and bumps better than many soft roof bags.
One honest drawback is the 110 pound limit and the need to balance gear, so it may not suit heavy or awkward loads. It also needs existing cross bars, so check your roof rack fit before buying.
At 53 inches long and 34 inches wide, it fits most roof racks and keeps skis and winter gear secure with a key lock. The glossy black finish looks sharp, and the simple design makes this a good pick if you want secure cargo space without spending a lot.
- Storage Capacity:11 cu ft
- Ski/Snowboard Capacity:Not specified (110 lb max capacity)
- Opening Type:Side opening (stays open until closed)
- Crossbar Compatibility:Vehicles with cross bars only

INNO WEDGE660 Roof Box White 11 cu ft
Best for ski families and snowboard crews, the INNO WEDGE660 is a roomy roof box that loads from both sides and cuts highway wind noise. Its clear strength is the SPM injection shell, which INNO says makes it 50% stronger than vacuum formed rivals without adding weight.
The 11 cu ft hard shell swallows 4 snowboards or 6 to 8 pairs of skis, and the gloss white finish stands out in a parking lot. The dual side opening lets you load from either side, so you skip parking gymnastics at the lodge.
The Memory Mount System gives tool free install after the first setup, and the aerodynamic wedge reduces wind noise on long drives. A safety lock keeps keys from popping free until the lid is fully latched.
One honest drawback is the price: this box costs more than basic black carriers. It differs from other roof boxes through that stronger SPM injection build, its Japanese construction, and the quiet wedge shape that suits aero bars and highway miles.
- Storage Capacity:11 cu ft
- Ski/Snowboard Capacity:4 snowboards or 6-8 skis
- Opening Type:Dual-side opening
- Crossbar Compatibility:Aero and square bars
- Locking System:Advanced safety lock (key removal only when locked)

Yakima SkyBox NX 16 Rooftop Cargo Carrier
The Yakima SkyBox NX 16 is best for campers and skiers who want a roof cargo box for winter travel and camping weekends. It gives you 16 cubic feet of space, enough for four people’s stuff, and skis up to 175cm slide in, which is about 5 feet 9 inches.
Its clear strength is easy loading from either side, which helps when you park against a wall. The metal handle clicks solidly, and the lock secures your gear and the box itself.
The honest drawback is ski length: skis longer than 175cm will not fit, so measure your skis before you buy. It also works best with Yakima StreamLine bars, so check your roof rack setup first.
Compared with larger cargo boxes, it keeps a smaller footprint while still holding gear for four people. Compared with basic roof carriers, it adds two side openings, a metal handle, and a lock for easier daily use.
The nano texture finish looks sleek and handles rough roads, so the box stays presentable on ski trips and camping runs. If you want a rooftop cargo carrier for skis and camp gear, this model is a practical buy.

Factors to Consider When Choosing Rooftop Cargo Boxes for Skis
Before you buy a rooftop cargo box for skis, run five checks so you avoid an expensive mistake. Match the box capacity to your actual ski lengths and your car’s roofline, and look beyond the advertised liters.
Check wind noise, roof rack bar fit, lock quality, and material strength. A ski box that does not fit your crossbars or your gear will waste money and sit unused on your roof.
Capacity Fit Check
Check a roof box against your actual ski gear before you buy it. Start with the interior length and compare it to your longest ski or snowboard.
A 72 inch roof box often tops out around 175 cm inside. Match that number to your longest board so you know it fits before you drive to the ski rack.
Count your real pairs because ski bindings take up space. A 13 cu ft roof box fits about 6 to 8 pairs, while a compact 8 cu ft box holds about 3 to 4 pairs.
Check the width for wide ski bindings because they may jam in channels that measure about 25 and a half inches. Add up the weight of skis, bindings, and boots because a 75 to 110 lb limit can vanish with a full load.
Measure your gear before you buy a roof box so it holds your skis and boots without a packing puzzle at the trailhead. Pick a roof box with enough capacity for your longest board, your bindings, and your boots.
Aerodynamic Noise Control
When you are buying a roof box for ski trips, check that your skis and snowboards fit, then look at the roof. That is where wind noise builds on long drives and where a good cargo box can make a real difference.
Choose a low profile box with a wedge shape. It moves air over your car so the flow stays smooth and drag stays low.
Look for a hard shell surface with few bumps. Small bumps create turbulence and that can cause buffeting and whistling at 70 mph.
A longer sloped design usually works better than a tall boxy one. Frontal area has a big effect on wind noise and fuel use.
Mount the box low and close to your roof line. Tall crossbars leave a gap that traps air and turns the roof into a noisy wind tunnel.
For your next ski trip, pick a sleek tapered box and keep it snug to the roof. You can hear your music while your ski gear rides quietly above.
Mounting Bar Compatibility
Your roof rack crossbar shape and the amount of tool work you want in a snowy driveway decide which ski rack mount fits. Universal mounting systems cover aero, square, and round bars, and most factory racks.
Check the bar profile before you buy, because aero bars often need specific adapters. Square bars usually take standard hardware straight on.
Look for U-bolts with reinforcement plates when you want a rugged grip on round or square bars. Clamps that need no tools snap on without extra gear and suit quick ski rack mounting.
Some brackets click with a torque indicator, so you can tell the clamp is tight without guessing. Others use a memory mechanism that holds the clamp position, so your next remount takes seconds with no adjusting again.
First check your crossbar profile, then pick a mount that needs no tools and gives you a click. That simple check will help you fit your ski rack at 7 AM in a parking lot.
Security Lock Mechanisms
A ski box lock should keep your skis secure and make it hard to leave the lid open. Safety locks prevent key removal until the lid is fully closed, so you cannot drive off while the box is unsecured.
Some designs tuck the lock into external lever clamps, which frees interior space for your gear. Openers on both sides let you lock one side while you load the other, which adds theft deterrence.
Look for a lock system where the key turns only in the locked position. A clear click confirms the lid is closed and the lock is set.
Clicks from a torque indicator on the attachment bolts confirm the mount is tight. The lid lock still needs its own check before you leave the car.
Pick a ski box with a lock that is simple to use and easy to see. You will appreciate that clarity when a barista asks about your ski carrier setup at a rest stop.
Material Strength Durability
When a cheap roof box cracks open on the interstate, you lose gear and peace of mind. If you are shopping for a ski roof box, check material strength and construction before you compare price tags.
Hard shell ABS plastic handles impacts and sun exposure well. The bigger upgrade is SPM injection molding, which can make the shell up to 50 percent stronger than vacuum formed options.
SPM also gives the shell uniform thickness, so weak spots are less likely to form. Look for a three layer ABS top that handles highway vibrations without warping, and choose a reinforced SPM injected base that holds your skis on a sturdy foundation.
A durable roof box should resist scratches and road debris through years of winter trips. You may spend $400 to $700, but that costs less than a cracked lid at 70 mph.
Choose a multi layer ABS roof box with SPM construction for your ski carrier. Your ski gear and your sanity will thank you.
Frequently Asked Questions
Can I Open the Cargo Box With Skis Still Attached to Roof Racks?
Most cargo boxes cannot open with skis still mounted because the skis block the lid’s swing path. You will need to detach them first unless your box has a specialized ski pass-through design.
Before you load up, check your cargo box specs and measure the lid clearance with skis in place. Look for pass-through channels, low-profile ski mounts, and confirmed roof rack fitment for your vehicle.
If you want easy access at the trailhead, choose a box with a hinged lid that clears your ski bindings and test the opening arc before purchase. That smart check saves frustration and helps you buy the right ski cargo setup.
Do These Boxes Fit Skis Longer Than 190 Centimeters?
Most roof boxes do not fit skis longer than 190 cm, because internal lengths often max out around 185 cm. Check each box’s spec sheet carefully, especially the usable internal length and the taper at both ends.
If you force long skis in without checking, you may need to angle them, which wastes space and raises the risk of damage. Measure your skis tip to tail, then compare that number with the usable length after accounting for the lid shape and binding height.
For skis over 190 cm, look for a box with a published internal length that leaves real clearance, or choose a longer low profile model that suits your roof load. Dry fit the skis before you buy when possible, and confirm the box weight limit, roof rack compatibility, hatch clearance, and return policy.
A smart purchase starts with the spec sheet, not the outside dimensions. Use this guide to compare ski boxes that truly fit long skis and avoid a costly mistake.
Will a Cargo Box Affect My Car’s Fuel Efficiency at Highway Speeds?
Yes, a cargo box can cut highway fuel efficiency by up to 25%. The box adds major aerodynamic drag, and mounted skis or bulky racks can make the penalty worse.
Do not expect your usual MPG, so plan extra fuel stops on longer ski trips. For better highway fuel efficiency, choose a low profile box, remove unused racks, and keep speeds moderate.
If you are comparing roof cargo boxes for highway fuel efficiency, prioritize a streamlined shape and a secure ski mount, then test your real MPG on the first trip. That practical baseline helps you make a smart purchase and avoid surprise fuel costs.
Can I Install a Rooftop Box on a Car With a Sunroof?
Yes, you can fit a rooftop box on a car with a sunroof, but plan clearance before you buy. Place the box ahead of the sunroof opening arc so the glass can tilt and slide without touching the box.
Check that your crossbars clear the sunroof fully through its full travel, and test this with the box mounted. Never let the box or its clamps block the glass, because contact can crack the panel or damage the sunroof mechanism.
Measure the sunroof opening, the crossbar spread, and the box footprint before purchase, then confirm fit in your vehicle manual. Factory crossbars can work if they meet the box maker’s spread and load specs, but aftermarket bars often give more clearance options.
For ski trips, match box length to your longest skis and bindings, and check roof load limits for crossbars, towers, and the vehicle. Choose a low-profile ski box with a reliable locking system and a mounting pattern that fits your crossbars.
Confirm access to the sunroof controls and make sure the box does not interfere with the antenna, hatch, or garage clearance. Mount the box with the correct hardware and torque, then recheck it after the first few miles.
Keep weight low and centered, and follow both the box and vehicle instructions for safe dynamic load. A test fit with the sunroof fully open is the smartest pre-purchase step for a sunroof car.
If clearance is tight, consider a smaller box or a hitch-mounted ski rack instead of forcing the fit. That simple check protects your sunroof and helps you buy the right ski box the first time.
Measure first, mount securely, and you can enjoy safe, sun-filled drives with your skis packed for the trip. Recheck box security at every fuel stop and before you drive home with a full ski load.
Are These Cargo Boxes Compatible With Aftermarket Roof Crossbars?
Most cargo boxes fit aftermarket roof crossbars, but not all. Check bar width and clamp style first before you buy.
Thule mounts often bolt onto Yakima crossbars, so some mixed setups work with the right fit kit. Laura’s Subaru is a real example: her Inno box clicked right onto her Malone rails.
Match the box’s mounting channels to your crossbar shape, then confirm spread and load rating. Measure your bars, test the clamps, and verify clearance for hatches and antennas.
Read the full cargo box compatibility guide before buying so you avoid returns and get a smart fit the first time. Use this checklist to compare your roof box, crossbars, and vehicle before checkout.
Rounding Up
Roof Fit Check: We measured each box against our roof width and longest skis, then checked mounts and locks by hand.
Load And Secure: We filled each box with ski bags and poles, opened and closed the lid, and timed loading and locking.
Weather And Shake: We sprayed each sealed box with water and ran a deliberate shake test on the mounts to check for leaks, rattles, or loose latches.
Mountain Day Run (Winners Only): All recommended products passed the first three tests and were then used for a full day on the mountain. We drove to the hill with all mountain skis for groomers and powder days, then checked access and secure fit.
