More Details on Our Top Picks

1. Thule Pulse 2 L Roof Mounted Cargo Box, 16 Cubic Feet

   

   Best Overall for Versatile Winter Road Trips

   View on Amazon

   The Thule Pulse 2 L excels in combining ample storage with user-friendly features, making it the ideal choice for winter road trips where quick access and weather resistance matter most. Compared to the Rooftop Cargo Box Carrier, it offers a slightly more refined design with dual-side opening, enhancing convenience during snowy conditions. Its 16 cubic feet capacity strikes a balance for families or gear-heavy travelers, though the lack of exact dimensions may make fitting on smaller vehicles tricky. The tool-free installation with a torque indicator simplifies setup, especially in cold weather, but the overall size might limit compatibility with compact cars. This model is perfect for those seeking reliable, weather-proof storage without sacrificing ease of use.

   Pros:

   • Large 16 cubic feet capacity for versatile gear storage
   • Easy tool-free installation with torque indicator for quick setup
   • Weather-resistant ASA-ABS material ensures durability in snow and rain

   Cons:

   • Lacks detailed dimensions, which could complicate fitting on smaller vehicles
   • Potentially limited compatibility with certain vehicle sizes due to size

   Best for: Families or individuals needing a large, weather-resistant cargo box with easy access during winter travel

   Not ideal for: Owners of compact cars with limited roof space, as the size may be incompatible or cumbersome

   • Capacity:16 Cubic Feet
   • Load Capacity:75 kg
   • Material:ASA-ABS plastic
   • Access:Dual-side opening

   Our verdict

2. Heavy Duty Lockable Car Roof Rack Cargo Carrier 110 LBS Capacity 53 x 34 x 15 Inches Black

   

   Best for Heavy-Duty Winter Cargo Needs

   View on Amazon

   The Heavy Duty Lockable Car Roof Rack Cargo Carrier provides robust security and high capacity, making it ideal for winter travelers hauling heavy or bulky gear. Its 110 lbs weight capacity surpasses many soft-sided options like the 21 Cubic Car Rooftop Cargo Carrier, offering a more secure, impact-resistant option. The lockable design adds peace of mind against theft during stops in snowy areas, but it’s limited to vehicles equipped with cross bars, which could exclude some. Its size—53 x 34 x 15 inches—fits most larger vehicles but might be cumbersome for those with smaller roofs or limited handling strength. This pick suits users prioritizing security and heavy load capacity over lightness or ease of installation.

   Pros:

   • Heavy-duty ABS construction resists impacts and weather
   • Secure key lock system prevents theft of valuable gear
   • Easy to install on vehicles with cross bars, increasing versatility

   Cons:

   • Limited to vehicles with existing cross bars, restricting compatibility
   • Heavy weight may be difficult for some users to handle during mounting

   Best for: Travelers with larger vehicles or those carrying heavy winter gear who want security and durability

   Not ideal for: Drivers of smaller cars or SUVs without cross bars, due to mounting restrictions and weight handling

   • Capacity:110 lbs
   • Dimensions:53 x 34 x 15 inches
   • Material:ABS plastic
   • Color:Black
   • Locking mechanism:Key lock
   Our verdict

   “This carrier is best suited for those needing a tough, lockable cargo solution for larger vehicles during winter months.”

3. 21 Cubic Car Rooftop Cargo Carrier Waterproof Roof Bag with Accessories

   

   Best for Flexible, Waterproof Storage

   View on Amazon

   The 21 Cubic Car Rooftop Cargo Carrier offers a soft-sided, waterproof alternative that adapts well to various vehicle types, making it a strong choice for winter road trips where flexibility and rain resistance are needed. Unlike rigid boxes like the Thule Pulse 2 L, it can be packed more tightly and stored when not in use, but it requires careful securing to prevent wind flapping, especially in snowy gusts. Its 21 cubic feet capacity exceeds many hard-shell options, accommodating multiple suitcases or bulky gear, yet the installation process can be tricky on windy days or for less experienced users. The included accessories, such as reinforced straps and an anti-slip mat, enhance security and stability, but the added weight of heavy-duty PVC might impact vehicle handling.

   Pros:

   • Highly waterproof and durable, protecting gear in snow and rain
   • Large capacity for multiple suitcases, perfect for family trips
   • Universal fit with included straps and accessories for easy setup

   Cons:

   • Requires careful tensioning and adjustment in windy conditions
   • Heavy-duty material adds weight, possibly affecting vehicle fuel efficiency

   Best for: Road trip enthusiasts seeking waterproof, flexible storage that adapts to different vehicle sizes and shapes

   Not ideal for: Travelers who prefer rigid, lockable storage or have limited roof space, as the soft bag may be less secure and bulky

   • Material:840D PVC
   • Capacity:21 cubic feet
   • Dimensions:52 x 40 x 18 inches
   • Includes:Anti-slip mat, luggage lock, reinforced straps, door hooks, storage bag
   Our verdict

   “This waterproof roof bag is excellent for flexible, rainproof storage on winter adventures, especially for those prioritizing adaptability over rigidity.”

4. INNO Roof Box 320 Matte Black 9 cu ft Cargo Box with Dual-Side Opening

   

   Best Compact Hard Shell for Easy Access

   View on Amazon

   The INNO Roof Box 320 stands out with its sleek, low-profile design and 9 cubic feet of space, making it ideal for winter trips where minimal wind resistance and style matter. Its dual-side opening enhances accessibility in snowy conditions, and the rugged matte black finish adds durability against winter elements. Compared with larger boxes like the Thule Pulse 2 L, this model sacrifices some capacity but offers easier handling and installation with the Memory Mount System, which is especially convenient on colder days. However, the limited size may fall short for larger families or extended trips, and the absence of detailed warranty info could be a concern for long-term durability. This box makes the most sense for solo travelers or couples with moderate gear needs.

   Pros:

   • Compact, low-profile design reduces wind drag
   • Dual-side opening offers convenient access from either side
   • Easy to install with Memory Mount System, suitable for Aero and Square bars

   Cons:

   • Limited storage capacity for larger groups or extended trips
   • Warranty details are not specified, which may concern some buyers

   Best for: Singles or couples requiring a compact, stylish, and easy-to-access cargo solution for winter travel

   Not ideal for: Large families or those with extensive gear, as capacity may be insufficient for bigger loads

   • Capacity:9 cu ft
   • Finish:Matte Black
   • Material:Hard Shell
   • Mounting System:Memory Mount System
   • Opening:Dual-Side
   Our verdict

   “This cargo box suits travelers needing a stylish, smaller hard shell with easy access for winter trips, especially on smaller vehicles.”

5. Rooftop Cargo Box Carrier, 12 Cubic Feet, Dual-Side Opening, 165 lbs Capacity, Black

   

   Best for Secure, Waterproof Storage for Moderate Loads

   View on Amazon

   The Rooftop Cargo Box Carrier offers a reliable balance of capacity and security, making it suitable for winter road trips with moderate gear loads. Its 12 cubic feet of space is comparable to the Thule Pulse 2 L, but with a focus on waterproof, UV-resistant ABS construction that keeps gear dry in snowy weather. The dual-side opening simplifies access in tight parking situations or snow-covered surroundings. While it’s compatible with all vehicles equipped with a roof rack, installation might be less straightforward for those unfamiliar with roof-mounted systems. Its 165 lbs capacity is ample for most gear, but the limited color options and the need for a roof rack could be drawbacks for some. This product is ideal for users who want a durable, secure cargo box without overcapacity.

   Pros:

   • Durable ABS construction resists impact and weather
   • Waterproof and UV-resistant, ideal for snowy conditions
   • Dual-side opening for easy access from either side

   Cons:

   • Requires existing roof rack for installation, limiting compatibility
   • Limited color options and possibly challenging to install for some users

   Best for: Vehicle owners with roof racks seeking a waterproof, secure cargo box for moderate winter gear loads

   Not ideal for: Car owners without roof racks or those needing extremely large capacity, as it requires roof rack compatibility and may be limited in volume

   • Material:ABS
   • Capacity:165 lbs
   • Storage Volume:12 cubic feet
   • Dimensions:54.3″L x 31.5″W x 13.4″H
   • Compatibility:All vehicles with roof rack
   Our verdict

   “This cargo box is well-suited for those needing a secure, waterproof storage solution for winter gear on vehicles with roof racks.”

6. Auto Dynasty Hard Shell Roof Top Mount Cargo Carrier – 53 x 34 x 15 Inches, 11 Cubic Feet, Heavy Duty with Security Keys

   

   Best Overall for Secure, Heavy-Duty Storage

   View on Amazon

   This cargo carrier stands out for its robust 11 cubic feet capacity and heavy-duty construction, making it ideal for winter road trips with bulky gear. Compared to the Yakima SkyBox NX 18, it offers a slightly smaller volume but benefits from a more straightforward, tool-free installation and a durable ABS shell that withstands harsh weather. Its security lock system provides peace of mind, yet it’s limited by the need to verify cross bar compatibility, which could complicate setup on some vehicles. The absence of insulation means it’s less suitable for temperature-sensitive items but excels in protecting gear from snow, ice, and impacts during winter driving. Overall, this pick is perfect for drivers prioritizing tough protection and security over sleek design or extra capacity.

   Pros:

   • Large 11 cubic feet storage capacity
   • Secure lock system for valuables
   • Weather-resistant and impact-protected

   Cons:

   • Requires checking cross bar width for fit
   • Limited to vehicles with suitable cross bars

   Best for: SUV owners needing rugged, secure storage for heavy winter gear and equipment.

   Not ideal for: Drivers with irregular cross bar widths or those seeking maximum capacity for large groups.

   • Dimensions:53 x 34 x 15 inches
   • Capacity:11 cubic feet
   • Weight Limit:110 lbs
   • Material:UV-protected, weather-resistant ABS
   • Installation:Tool-free, fits cross bars up to 13 inches wide

7. Yakima SkyBox NX 18 Roof Top Cargo Carrier, 18 Cubic Feet, Black

   

   Best for Convenience and Modern Design

   View on Amazon

   The Yakima SkyBox NX 18 offers a generous 18 cubic feet of storage, making it well-suited for winter road trips involving skis, snowboards, or multiple bags. Its dual-sided opening simplifies loading, especially when vehicles are parked in tight spaces, while the SKS lock system enhances security for valuables. Compared with the Auto Dynasty, it boasts a sleeker, more aerodynamic profile and a modern nano-texture finish that resists scratches and weathering. However, its weight and installation complexity may pose challenges for solo setup, limiting convenience for some users. Its slightly higher price reflects its premium build and ease of access, making it a better fit for those valuing quick, secure access over lower-cost options.

   Pros:

   • Large 18 cubic feet capacity
   • Dual-sided opening for easy access
   • Secure SKS lock system
   • Sleek, durable nano-texture finish

   Cons:

   • May be heavy to install alone

   • Color:Black
   • Fits skis up to:195cm
   • Opening:Dual-sided
   • Locks:SKS locks
   Our verdict

8. TUFFIOM 13.4 cu.ft. Rooftop Cargo Box with Keys, Waterproof Hard Shell Travel Roof Storage Carrier

   

   Best for Versatile, Waterproof Protection

   View on Amazon

   This 13.4 cubic feet cargo box offers a balanced mix of weatherproofing and ease of access, making it suitable for winter road trips where staying dry is critical. Its dual-side opening simplifies loading, especially when parked on snow or ice, while the waterproof ABS shell shields contents from snow, slush, and moisture. Compared with the Rooftop Cargo Box (B0F197LN4K), it supports a higher weight limit of 150 lbs, accommodating heavier gear. Still, the installation can be challenging for beginners, and peeling off protective film is an extra step before use. Its universal crossbar compatibility broadens its appeal, but it may add to setup time. This model fits drivers seeking reliable weatherproof protection combined with straightforward functionality.

   Pros:

   • Easy dual-side access
   • Secure locking with keys
   • Waterproof ABS shell offers excellent weather protection
   • Compatible with most vehicles

   • Max Load Capacity:150 lbs
   • Material:ABS

   Best for Extra Large, Weatherproof Cargo Space

   View on Amazon

   This 14.5 cubic feet cargo box offers substantial storage for winter gear, with easy, no-drill installation suited for those who want quick setup on cold, snowy days. Its UV-protected ABS material resists cracking and fading, ideal for long-term outdoor use. Compared with the TUFFIOM box, it supports a slightly lower maximum load of 125 lbs but compensates with a more aerodynamic shape that reduces wind resistance and noise during highway travel. Its lockable feature secures your gear from theft, which is especially useful in remote winter destinations. The main tradeoff involves its weight capacity limits and potential wind noise, which might impact comfort on extended drives. This makes it a solid choice for travelers needing large, reliable, weather-resistant storage that’s simple to install.

   Pros:

   • Large 14.5 cubic feet capacity
   • Weatherproof and lockable
   • Easy, drill-free installation

    This 13 cubic feet cargo box strikes a balance between capacity and ease of use, making it well-suited for family winter trips. Its dual-sided access simplifies loading and unloading, even in snowy conditions, while the impact-resistant ABS and PMMA construction ensure durability against winter weather. Compared to the TUFFIOM model, it supports a slightly lower weight limit of 130 lbs but offers a straightforward installation process with universal brackets. Its weather-resistant features make it a practical choice for carrying luggage, snow gear, or camping supplies, though it’s a bit heavier to handle alone. This carrier is ideal for those looking for dependable, balanced storage without the frills of a premium, high-capacity model.

    Pros:

    • Durable and weather-resistant
    • Dual-sided access for convenience
    • Secure locking system

11. SportRack Vista XL Rear Opening Cargo Box

    

    Best Overall for Versatile, Large Capacity Storage

    View on Amazon

    The SportRack Vista XL stands out for its generous 18 cubic foot capacity and durable UV-resistant ABS construction, making it a reliable choice for winter road trips with bulky gear. Its rear-opening design provides convenient access without the need to climb onto the roof, a notable advantage over models like the Hard Shell Roof Cargo Box 21 Cubic Feet, which offers more space but requires more effort to access. The tool-free mounting system simplifies installation, yet the box can be heavy to handle alone—potentially challenging for smaller vehicles or solo travelers. Compatibility depends on your rack system, so verifying dimensions beforehand is essential. Compared to soft-shell options, this hard shell provides better weather protection but at a higher weight and cost. Ideal for those needing large, durable storage with straightforward access during winter trips.

    Pros:

    • Large 18 cubic foot capacity for extensive gear
    • UV-resistant, durable ABS material
    • Rear opening for easy access

    Cons:

    • Heavy to handle alone, especially during installation
    • Fits only specific rack systems, requiring compatibility checks

    Best for: Families or groups carrying bulky winter gear who prioritize capacity and durability.

12. Sailnovo Rooftop Cargo Carrier Roof Bag, 20 Cubic Feet, Waterproof, Foldable, Includes 6 Tie-Down Straps and Door Hooks

    

    Best for Flexible, Soft-Shell Storage on a Budget

    View on Amazon

    The Sailnovo Roof Bag offers a large 20 cubic feet capacity suitable for multiple suitcases and winter gear, making it an appealing soft-shell alternative to rigid boxes like the Hard Shell Roof Cargo Box 21 Cubic Feet. Its waterproof 1000D Oxford cloth ensures gear stays dry in snow and rain, while the foldable design means it can be stored compactly when not in use—an advantage over bulky hard-shell models. However, soft bags like this require careful filling to prevent water pooling and may overhang on smaller vehicles, especially those without roof racks or with limited space. Installation is straightforward with included straps and hooks, but it’s best suited for vehicles with existing roof racks, unlike the Garvee Rooftop Cargo Box, which offers a more weatherproof solution. This soft-shell carrier is ideal for budget-conscious travelers who want flexible, waterproof storage.

    Pros:

    • Large 20 cubic feet capacity for multiple items
    • Waterproof and tear-resistant material for weather protection
    • Foldable for convenient storage

    Cons:

    • Not recommended for vehicles without roof racks
    • Requires proper filling to prevent water pooling
    • Potential overhang on small or compact cars

    Best for: Travelers needing a waterproof, foldable option that can be stored easily when not in use.

    Not ideal for: Owners of small cars or those without roof racks, due to overhang risks and installation challenges.

    • Capacity:20 cubic feet
    • Material:1000D Oxford cloth
    • Dimensions:51″ (L) x 39″ (W) x 17″ (H)
    • Includes:6 tie-down straps, 6 door hooks

    Best for Weather-Resistant, Easy-Access Hard Shell Storage

    View on Amazon

    The Garvee Rooftop Cargo Box combines a sturdy 12 cubic foot capacity with dual-sided opening for quick access from either side, making it a practical choice for winter road trips. Its waterproof, UV-resistant ABS shell offers reliable weather protection, comparable to the Hard Shell Roof Cargo Box 21 Cubic Feet, but with a smaller capacity suited to those who prioritize accessibility and security. The locking system adds peace of mind, yet verification of your vehicle’s roof rack compatibility is necessary before purchase. It’s a solid choice for travelers who want durable, weatherproof cargo space without the bulk of larger boxes. The limited capacity may not suffice for larger families or extended trips, but for solo or couple trips, this box offers a good balance of weatherproofing and ease of use. Ideal for those seeking a weatherproof, lockable hard shell with easy dual-side access.

    Pros:

    • Weather-resistant, UV-protected ABS shell
    • Dual-side opening for quick access
    • Secure locking with keys

    Cons:

    • Limited to 12 cubic feet, less suitable for large groups
    • Requires roof rack verification for compatibility

    Best for: Travelers needing secure, weather-resistant cargo with easy access on vehicles with compatible roof racks.

    • Material:ABS
    • Opening:Dual-side
    • Color:Black
    • Warranty:1 Year

    Best for Maximum Storage and Weather Resistance

    View on Amazon

    The Hard Shell Roof Cargo Box 21 Cubic Feet provides the largest capacity in this lineup, making it ideal for winter road trips with extensive gear. Its high-gloss ABS and PC composite construction enhance durability and fuel efficiency, while dual-side opening ensures easy access regardless of vehicle size. Compared to the SportRack Vista XL, it offers more storage space, but it can be heavier and more expensive, which may complicate handling and installation. Its secure central locking system adds an extra layer of security, though it requires a vehicle equipped with compatible roof bars. This model suits those who need maximum capacity and weather protection, especially on longer trips, but less so for those seeking lightweight or budget options. Best suited for large families or serious outdoor enthusiasts with ample gear to carry.

How We Picked

Products were evaluated based on capacity, weather resistance, ease of installation, build quality, security features, and user convenience. Priority was given to models that perform reliably in winter conditions—such as waterproof seals, sturdy shells, and secure locking mechanisms—since these are essential for protecting gear from snow, ice, and moisture. We also considered value, balancing features with cost, and versatility, including options that suit different vehicle types and levels of experience. The ranking reflects a combination of these factors, emphasizing durability and usability for winter road trips over sheer capacity alone.

Factors to Consider When Choosing Roof Cargo Box For Winter Road Trip

Choosing the right roof cargo box for winter travel involves balancing capacity, weather resistance, and ease of use. Considering these factors can prevent common frustrations like difficulty handling in snow, inadequate sealing, or installation challenges. The right model depends on your vehicle size, trip length, and the amount of gear you need to carry. Being aware of tradeoffs between size, weight, and security can help you make a smarter choice that enhances your winter driving experience.

Capacity and Size

Understanding how much gear you need to carry is the first step. Larger cargo boxes can hold more equipment such as skis, snowboards, and winter clothing, but they also add weight and may impact your vehicle’s handling in snowy conditions. Smaller, more compact options are easier to install and manage, especially if you’re new to roof storage. Think about your typical trip length and gear volume to align with a size that balances space and practicality.

Weatherproofing and Durability

Winter conditions demand a cargo box that can withstand snow, ice, and moisture. Look for models with high-quality, weatherproof seals, corrosion-resistant shells, and robust locking mechanisms. Cheaper or poorly sealed options risk letting snow or water seep in, damaging your gear. Investing in a well-made, durable shell can save you from costly damages and frustration during cold weather adventures.

Ease of Installation and Access

In winter, quick and secure installation is a major advantage, especially if snow or ice complicates setup. Dual-side opening features make it easier to access your gear without climbing onto the vehicle, which can be tricky in cold or slippery conditions. Also, consider how easily the box can be secured to your roof rack—an awkward or complicated system can detract from your trip planning.

Security and Locking Features

Since winter trips often involve remote areas, a cargo box with reliable locks adds peace of mind. Heavy-duty locking mechanisms help prevent theft and keep the contents secure during stops. Some models include security keys or reinforced shells, which are especially useful when leaving gear unattended in cold or isolated locations. Weigh the importance of security against added weight and complexity.

Cost and Value

Price ranges widely across options, with premium models offering advanced features like aerodynamic design, enhanced security, and superior weatherproofing. While investing more can result in better durability and ease of use, budget models may suffice for occasional winter trips. Consider how often you’ll travel in winter and whether the added cost aligns with the benefits you seek, such as reliability in harsh conditions.

Frequently Asked Questions

Will a standard roof cargo box hold up in heavy snow or ice?

Most modern roof cargo boxes designed for winter use are built with weather-resistant materials and sealed closures that can handle snow and ice. However, their performance depends on the quality of construction; cheaper models may crack or leak under extreme conditions. Regularly clearing snow from the box surface and ensuring it is securely fastened can prolong its lifespan and maintain performance during winter trips.

Is it better to choose a hard-shell or soft-shell roof cargo bag for winter travel?

Hard-shell cargo boxes tend to provide better protection against snow, ice, and moisture, making them a preferred choice for winter road trips. They are usually more durable and secure, especially in freezing temperatures. Soft-shell bags, while lighter and more flexible, are less resistant to water ingress and damage from snow. For cold, snowy conditions, a hard-shell box offers greater peace of mind and longevity.

How much additional weight can my roof support in winter? Does snow accumulation matter?

Most vehicles have a roof weight limit specified by the manufacturer, often ranging from 165 to 220 pounds, including the cargo box and contents. Snow accumulation adds extra weight, so it’s wise to clear snow regularly during stops. Overloading the roof can impact handling and safety, especially on icy or snowy roads. Always check your vehicle’s roof load capacity before loading a heavy cargo box or accumulating snow.

What features should I prioritize for winter storage in a roof cargo box?

Prioritize weatherproof seals, durable construction, and secure locking mechanisms. Dual-side opening can be especially helpful when access is limited or in cold weather. Also, look for models with aerodynamic design to reduce wind resistance and improve fuel efficiency. These features collectively enhance safety, convenience, and protection during winter trips.

Is it necessary to buy a larger cargo box for winter trips compared to summer?

Not necessarily—your gear needs often stay the same regardless of season. However, winter gear like skis, snowboards, and bulky clothing can require more space. If your current box is too small to fit winter equipment comfortably, upgrading to a larger model makes sense. Otherwise, selecting a well-sized, weather-resistant box that fits your gear is more important than size alone.
