This lockable storage box is roomy enough to hold up to two XL helmets and provides additional interior space for tools or accessories. With double-wall lid construction, the box gains rigidity to support added weight from any optional accessory rack sold separately. It is a solid option for riders who prioritize helmet storage and reliable durability on rugged trails.
Black Boar ATV Rear Storage Box & Lounger

This configuration combines a rear storage box with a cushioned lounger, delivering comfort and practical storage. The design is compatible with most tubular racks, and the internal hardware is included for straightforward mounting. It offers approximately two cubic feet of space across two cargo boxes, with a sealed lower bin and a smaller upper bin accessible from the seated position. The setup is ideal for riders needing both seating and organized cargo compartments while riding.
Kolpin ATV Rear Helmet Box

Kolpin’s helmet box offers heavy-duty rotomolded construction with UV stabilization for outdoor durability. The rear-opening design provides accessible arm cavities, and the box mounts easily to many tubular ATV racks using the included four U-bolts and sealing washers. This option is well suited for riders who want dedicated helmet protection and robust mounting hardware.
Guide Gear ATV Lounger Seat With Storage

The Guide Gear ATV lounger provides a rear-mounted seat with a substantial storage compartment behind the rider. Designed for tubular racks, the unit includes accompanying fixtures and provides space for two helmets or other large items. It emphasizes comfort while enabling organized storage, making it a practical choice for longer rides or family trips where passenger seating is required along with cargo space.
Polaris Lock & Ride Rear Open Cargo Storage Box

The Polaris Lock & Ride system enables fast installation and removal of a rear open cargo box, expanding storage by 22 gallons. It integrates with Lock & Ride anchors and plugs as needed and is compatible with rack extenders and gun mounts. Two integrated 5-gallon bucket holders add practical transport options for liquids or additional tools, making it a versatile solution for versatile, modular storage needs on sport and utility ATVs.
Buying Guide: Key Considerations For Selecting ATV Rear Storage
- Capacity and layout: Determine how much gear you typically carry and whether you need separate compartments, helmet storage, or a combination seating solution with storage.
- Mounting compatibility: Check rack type (tubular or fixed) and whether the storage box includes hardware for your model. Quick-disconnect options are convenient for frequent accessorization.
- Durability and weather resistance: Look for rotomolded or double-wall construction, UV stabilization, and weatherproof seals to protect contents from sun, dust, and rain.
- Accessibility: Consider rear-opening doors, front access, or removable storage to minimize effort when loading and retrieving items on the trail.
- Security: Lockable lids improve security against theft and tampering, especially for helmet storage or valuable tools during longer stops.
- Comfort and combined use: If you need seating, ensure foam padding, backrests, and fitment with minimal interference to riding posture and handlebars.
- Maintenance and cleaning: Materials that resist tears and are easy to wipe down help when frequently exposed to mud and grime.
- Brand ecosystem and support: Reputable brands with compatible accessories (racks, racks extenders, inserts) simplify upgrades and replacements over time.
In evaluating these options, riders typically balance helmet storage capacity versus seating comfort, while considering how easily the box can be mounted on their ATV’s rack. For shared-use setups or family trips, a lounger with storage can offer dual benefits, whereas dedicated helmet boxes prioritize gear protection. For those prioritizing quick setup and removal, Lock & Ride style systems provide modular flexibility that suits frequent changes in cargo configuration.
