Kolpin Rear Trail Box

The Kolpin Rear Trail Box combines a practical hard-shell design with a contoured shape that reduces sight obstruction while operating an ATV. This lockable storage box is sized to accommodate two XL helmets, offering substantial internal space for gear and personal items. A double-wall lid construction adds rigidity and supports additional weight if the optional accessory rack is used. The box is designed to mount securely to many ATV rear racks, making it a versatile option for trail riders who prioritise protection against rain and dust.
Key considerations include its secure locking mechanism, durably built lid, and the ability to add accessories for expanded setup. The contoured profile helps maintain visibility and maneuverability, which can be important for tight trails and slow-speed navigation. Users should confirm compatibility with their specific ATV rack and any added accessories before purchase. Overall, this box offers a balance of security, capacity, and weather protection for day trips and weekend adventures.
Black Boar ATV Rear Storage Box & Lounger

The Black Boar Rear Lounger combines seating comfort with integrated storage on ATV tubular racks. This design supports both comfort and gear access on the trail. The package includes installation hardware and internal organization features, with a lower lockable bin offering about 1 ½ cubic feet of sealed storage and an upper bin of about ½ cubic foot, reachable while seated. This approach provides layered storage for tools, snacks, or small accessories while keeping a cushiony seat for longer rides.
Compatibility with most tubular racks helps simplify installation, and the dual-bin setup can help separate dry items from more sensitive gear. This product is well-suited for riders who want a built-in seat without sacrificing significant cargo space, though it may require removing or relocating some items when accessing the lower storage. The design aims to deliver a compact, comfortable, and practical rear storage solution for ATV enthusiasts.
ATV Trunk & Lounger

The ATV Trunk & Lounger focuses on maximizing dry storage with an expansive 31-gallon (117-liter) capacity and a seamless hinge and gutter design to keep the interior dry and dust-free. The roto-molded construction emphasizes durability and weather resistance, making it a robust option for varied terrain and weather conditions. The design supports organized packing for long trips and can help keep gear protected from moisture and debris while riding or when parked outdoors.
Prospective buyers should evaluate whether the trunk’s size fits their rear rack width and whether the interior layout accommodates their typical gear. The unit’s USA-made construction (with global materials) reflects a balance of domestic manufacturing and global sourcing, often appealing to riders seeking durable, long-lasting storage. This trunk and lounger combination is especially suitable for riders who prioritize large capacity and weatherproof protection in a rugged ATV setup.
SUNPIE Soft Cargo Bags With Seats Cushion

SUNPIE offers a soft cargo bag system with a seats cushion pad and a replaced zipper design for improved durability. The rear seat bag provides up to 70 liters of expandable storage (5,000 cubic inches), with a braided strap surface to secure longer tools or equipment. The bags are crafted from premium 600 denier material, delivering water resistance and weather-tight sealing to protect stored items from rain and dust during varied riding conditions.
Important considerations include the suitability for four-wheel rear racks and the overall weather resilience of the material in muddy or wet environments. The soft design offers flexibility for fitting around existing racks and gear but may provide different protection levels compared to hard-shell boxes. This option suits riders who want easy access to contents while maintaining a lower profile and a cushion seat for added comfort on longer rides.
VEVOR ATV Rear Storage Bag

The VEVOR 68L rear storage bag combines a large storage area with a sponge seat cushion for comfort. Made from 600D Oxford cloth, it offers dust and wear resistance, designed to withstand rough outdoor conditions. The bag also includes a bottle holder pocket, supporting hydration needs during extended rides. The combination of seating and cargo space makes it a practical option for riders who want to carry essentials alongside a comfortable seating surface.
Its practical design emphasizes utility and durability, but users should verify fit on their specific rear rack configuration and ensure the seat cushion and strap system align with their riding style and rack geometry. The VEVOR model aims to provide reliable storage with convenience features for everyday trail use and weekend excursions.
Buying Guide: Key Purchase Considerations And Comparisons
- Capacity vs. footprint: Evaluate whether you need vast dry storage, seating integration, or a balance of both. Large trunks offer more space but may be heavier or bulkier, while soft bags can be more flexible but provide less rigid protection.
- Material and weather sealing: Hard-shell boxes typically provide stronger protection against moisture and dust, while soft bags rely on weatherproof fabrics and seals. Consider your typical riding conditions and climate.
- Compatibility: Confirm that the box or bag fits your ATV’s rear rack dimensions and mounting system. Some products include hardware, while others rely on universal mounting options.
- Security: A lockable lid adds security for valuables when the ATV is unattended. If theft protection is a priority, choose models with robust locking mechanisms and durable construction.
- Access and ergonomics: Consider whether you need front or rear access, and whether you’ll access storage while seated. Loungers may provide easier reach to gear but require more space.
- Durability and weight: Heavier hard-shell trunks may offer better protection but could affect balance. Lighter soft bags may be easier to manage but offer less impact protection.
- Installation effort: Some options are quick to install with existing mounting hardware, others may require drilling or adjustments. Check installation instructions and confirm compatibility with your ATV model.
- Maintenance: Look for water-resistant seals, removable liners, and easy-to-clean interiors. Consider how often you’ll clean mud, dust, or moisture from gear storage areas.
- Pricing and warranty: Compare long-term value, including warranty coverage, manufacturing quality, and replacement part availability.
Across these options, riders should align product choice with their typical trips, rack compatibility, and preferred balance of storage vs. seating. For heavy or long-duration use, hard-shell trunks with weather seals tend to offer better protection. For flexible packing and quick access, soft bags and loungers can be advantageous. Evaluating these dimensions helps identify the best rear cargo solution for ATV enthusiasts seeking reliable, organized, and weather-ready storage.
