1. Kolpin 20030 Outdoorsman Gear Box: Best All-Around Cargo Box
The Kolpin 20030 Outdoorsman Gear Box is a popular choice for riders who need a rugged, waterproof cargo box. In our evaluation, the UV-stabilized polyethylene shell held up well against impacts and sun exposure, and owner feedback consistently praises its weather sealing. The 20-gallon capacity fits a weekend’s worth of gear, and the gas strut makes access convenient even when mounted high.
However, some owners report that the gas strut loses tension over time, causing the lid to drop. This is not a dealbreaker for most, but those who plan to open and close the box frequently may want to budget for a replacement strut. If you need a lighter, flexible storage option, consider a soft bag instead.
- 20-gallon sealed storage keeps gear dry and secure
- Mounts to standard rear racks with included hardware
- Easy-open latches and gas strut lid support
Pros: Durable construction resists cracking in cold weather; Sealed lid prevents water intrusion during heavy rain
Cons: Lid strut can fail after extended use
2. Tusk Atlantis Cargo Box: Best Value Large Capacity
The Tusk Atlantis Cargo Box offers a high capacity at a budget-friendly price point. In our comparison, the polypropylene shell is lighter than polyethylene but also more prone to flex under heavy loads. Owner feedback indicates the waterproof seal is adequate for light rain but may leak in a downpour. The quick-release mount is a standout feature, letting you detach the box in seconds.
That said, the plastic hinge and latch feel less durable than on higher-priced models. If you frequently carry heavy, abrasive gear or ride in extreme conditions, you may want a sturdier box. This is best for casual trail riders who need occasional extra storage without breaking the bank.
- Large 35-liter capacity for bulky items
- Tool-free quick-release mounting system
- Reflective safety stripes for low-light visibility
Pros: Very affordable compared to similar sized boxes; Quick-release mount is convenient for removal
Cons: Plastic feels less robust than premium competitors
3. Genuine Yamaha Accessories Cargo Box: Best OEM Fit
The Genuine Yamaha Accessories Cargo Box is designed as a direct OEM upgrade for Yamaha ATVs. In our research, the ABS plastic is durable and color-matched to match the vehicle, and installation is straightforward with no modifications needed. The key lock provides peace of mind when leaving gear unattended on the trail.
However, the 20-pound weight limit is lower than many aftermarket boxes, and the 25-liter capacity may feel small for longer trips. If you own a Yamaha and prioritize aesthetics and security over maximum capacity, this is a solid choice. Riders of other brands should look at universal options.
- Color-matched to Yamaha ATV models for seamless look
- Key-locking lid for security
- Mounts directly to Yamaha rear racks without adapters
Pros: Perfect factory fit and finish; Locking lid adds security for valuables
Cons: Lower weight capacity limits heavy loads
4. Kolpin 20020 Outdoorsman Gear Bag: Best Soft Storage Bag
The Kolpin 20020 Outdoorsman Gear Bag is a soft-sided alternative for riders who need a flexible, lightweight storage solution. In our evaluation, the 600-denier polyester with PVC backing is water-resistant, and the roll-top closure keeps gear dry even in heavy rain. The MOLLE webbing allows customization with additional pouches, making it versatile for hunting or camping.
On the downside, soft bags offer little protection against impacts or theft. Items inside can be crushed if the ATV tips, and the bag cannot be locked. If you carry fragile or valuable items, a hard box is a better choice. This bag is ideal for bulky soft goods like clothes or sleeping bags.
- Lightweight and collapsible when not in use
- Roll-top closure keeps contents dry
- MOLLE webbing for attaching extra pouches
Pros: Very lightweight and easy to store; Roll-top provides excellent water resistance
Cons: Not lockable; less secure than hard boxes
5. Curtis 1900 Steel ATV Cargo Rack: Best Heavy-Duty Rack
The Curtis 1900 Steel ATV Cargo Rack is built for hauling heavy, bulky items like fuel cans, coolers, or game. In our comparison, the welded steel frame and powder coat finish offer exceptional durability, and owner feedback confirms it withstands rough trails without bending. The 150-pound capacity is among the highest in its class, and the universal mounting brackets fit most ATV racks.
However, the rack itself is heavy (over 10 pounds), which can affect handling on smaller ATVs. It also does not provide any enclosure, so items must be strapped down and are exposed to weather. If you need a lockable, weatherproof box, this is not the right choice. It is best for utility-focused riders who prioritize load capacity.
- Welded steel frame with black powder coat finish
- Bolts to existing rear rack with universal brackets
- Integrated tie-down loops for securing cargo
Pros: Extremely high weight capacity for heavy loads; Rugged steel construction lasts for years
Cons: Heavy; adds significant weight to the ATV
6. Seizmik Rear Cargo Bag: Best Waterproof Bag
The Seizmik Rear Cargo Bag is designed for riders who face extreme wet conditions. In our research, the welded PVC tarpaulin and roll-top closure provide a true waterproof seal, and owner reviews confirm it keeps gear dry even during river crossings. The 30-liter capacity is ample for a day trip, and the D-rings make mounting simple.
However, the PVC material becomes noticeably stiff in cold temperatures, making the bag harder to pack and close. The lack of internal organization can also make finding small items frustrating. If you ride in warm climates or need quick access to gear, a hard box or bag with pockets may be more practical. This bag is best for wet-weather adventurers.
- Fully submersible waterproof construction
- Roll-top and buckle closure for secure seal
- D-ring tie-down points for easy mounting
Pros: 100% waterproof even when submerged; Lightweight and easy to remove
Cons: PVC material can become stiff in cold weather
7. Pro Armor Rear Storage Box: Best for Sport ATVs
The Pro Armor Rear Storage Box is tailored for sport ATV owners who want minimal visual impact. In our evaluation, the compact 12-liter size fits small tools, a phone, and a wallet without sticking out. The rubber gasket keeps dust out on dry trails, and the molded plastic is lightweight enough not to affect handling.
But the 15-pound weight limit and small capacity mean you cannot carry much more than the basics. The latch feels somewhat flimsy, and some owners report it can pop open on rough terrain if not secured with a bungee. If you need to carry more gear or want a more robust latch, look at larger boxes. This is best for short rides where only a few items are needed.
- Compact low-profile design for sport ATVs
- Rubber gasket seal for dust and moisture resistance
- Includes mounting hardware for most rear racks
Pros: Low profile maintains sporty look and clearance; Good dust and moisture protection for trail use
Cons: Small capacity limits use to essentials only
Frequently Asked Questions
How do I choose between a hard cargo box and a soft bag for ATV rear storage?
Hard boxes offer better security, impact protection, and weather resistance, making them ideal for valuable or fragile items. Soft bags are lighter, more flexible, and easier to store when not in use, but they provide less security and can be crushed. Consider your typical cargo and riding conditions to decide.
Will a rear storage box fit on any ATV?
Most universal boxes and bags come with adjustable mounting brackets that fit standard rear racks. However, some ATVs have unique rack shapes or limited space. Always check the product dimensions and mounting hardware compatibility. OEM-specific boxes are designed for particular models and offer the best fit.
What is the maximum weight I should carry in an ATV rear storage box?
The weight limit depends on the storage unit and your ATV’s rack capacity. Most cargo boxes have a limit between 15 and 50 pounds, while heavy-duty racks can handle up to 150 pounds. Exceeding the limit can damage the storage unit or affect vehicle handling. Always check both the product and ATV specifications.
How do I keep my ATV rear storage box waterproof?
Look for boxes with a rubber gasket or O-ring seal on the lid, and ensure the latch closes tightly. Some boxes have drain plugs. For soft bags, roll-top closures provide excellent waterproofing. Applying silicone grease to gaskets can help maintain the seal over time.
Can I lock my ATV rear storage box to prevent theft?
Many hard boxes come with a built-in key lock or padlock hasp. Soft bags typically cannot be locked. For added security, you can use a cable lock through the box’s tie-down points or mounting holes, but no storage is completely theft-proof on the trail.
Our Verdict
After comparing specs, safety standards, and owner feedback, the Kolpin 20030 Outdoorsman Gear Box earns our top pick for its balance of durability, weather resistance, and ease of use. For budget-minded riders who need more capacity, the Tusk Atlantis Cargo Box offers great value with its large 35-liter size and quick-release mount.
