Picking rear storage for an ATV is a classic powersports luggage decision, especially when two adult helmets need a home behind the rider. Two rear trunk options look similar from a distance: the Kolpin ATV Rear Passenger Seat Cargo Storage Helmet Trunk Box Luggage Lounger and the 82L ATV Rear Passenger Pad Seat Cargo Storage Helmet Trunk Box Luggage Lounger. The two differ in interior volume, mounting notes, and a handful of convenience features. Here's how to choose between them.
Quick Verdict
Choose the Kolpin for a more feature-packed rear trunk. Choose the 82L if you want a simple ATV box and are prepared to drill for installation.
Comparison Table
| Product | Listed Price | Capacity | Mounting Note | Price Bar |
|---|---|---|---|---|
| Kolpin ATV Rear Passenger Trunk | USD 259.95 | 117 L | Hardware included for tubular racks | |
| 82L ATV Rear Passenger Pad Seat Trunk | USD 249.99 | 82 L | Drill holes required |
Where Each Product Wins
- Kolpin wins on finish details: removable no-slip seat pads, integrated padlock holes, heavy-duty rubber draw latches, and a seamless hinge and gutter.
- The 82L box wins on listed price and universal simplicity. It's the lower-priced option, a universal fit for ATVs with black LLDPE construction. The tradeoff is that installation requires drilling holes.
Product Notes
Kolpin ATV Rear Passenger Seat Cargo Storage Helmet Trunk Box Luggage Lounger

This Kolpin trunk is the higher-priced option, but it includes a seamless hinge and gutter design plus roto-molded construction. The limitation is mounting: hardware is included for tubular-style racks only, and Polaris or Can-Am racks will require custom mounting. If your ATV has a tubular rear rack, this is the more feature-packed choice.
82L ATV Rear Passenger Pad Seat Cargo Storage Helmet Trunk Box Luggage Lounger

This black trunk is a universal fit for ATVs with LLDPE construction and comes with a rear passenger pad seat. The main drawback is the smaller interior; it won't hold as much as the Kolpin. It also carries a California Proposition 65 warning. For riders who don't need the extra volume, this one fits the bill.
Final Choice by Use Case
If you frequently carry two helmets and want the extra features, choose the Kolpin at USD 259.95. If your priority is the lower listed price, choose the 82L at USD 249.99.
