An overland box is a rugged, weatherproof storage case built to carry gear on off-road and expedition vehicles. Eylar overland storage boxes feature IP67-rated perimeter gasket seals, a pressure-equalization valve, TSA-approved locking points, and stackable heavy-gauge aluminum or roto-molded shells that mount to roof racks, truck beds, and trailers.
Off-Road & Overlanding Storage Boxes — Built for Every Expedition
Eylar overland storage boxes are engineered for the demands of serious off-road travel: weatherproof gasket seals, heavy-gauge aluminum or roto-molded construction, pressure-equalization valves, TSA-approved locking points, and customizable pluck-and-pull foam inserts that protect every piece of gear from trail to camp. Whether you need a stackable overlanding storage box for a roof rack, a low-profile offroad storage box for truck-bed slats, or a modular hard case storage box system for a full basecamp build, this collection covers every configuration.
- Weatherproof perimeter gasket — seals out dust, mud, and rain on every overland cargo box
- Pressure-equalization valve — prevents vacuum lock at altitude or after temperature swings
- TSA-approved locking points — keep your kit secure at trailheads, campsites, and overnight stops
- Aluminum & roto-molded shell options — corrosion-resistant, stackable, and rack-mountable
- Customizable foam inserts — pluck-and-pull configuration adapts to any gear loadout

Overland Storage Boxes for Off-Road Rigs
Eylar's overland storage boxes line covers every build style: a universal overland storage box that mounts to standard roof racks and truck beds, stackable overlanding storage boxes for trailers and basecamp builds, and a rugged storage box for gear that rides outside in the weather. Many of our heavy duty cargo cases pair with a removable storage tray insert to keep recovery straps, tools, and kitchen gear separated, and XL case sizes fit full recovery kits. Choose a metal case in heavy-gauge aluminum or a roto-molded shell to match your rig — capacity options range from compact off road storage boxes up to XL cases and 50 L chest-style boxes for complete overlanding storage setups.

Overland Storage Box FAQs
What is an overland storage box?
An overland storage box is a stackable, lockable cargo case built to secure gear on off-road vehicles. Eylar's aluminum and roto-molded options include IP67-rated gasket seals, pressure-equalization valves, TSA-approved locking points, and customizable pluck-and-pull foam, and mount to roof racks, truck beds, and trailers.
Are overland storage boxes waterproof?
Yes. Eylar overland storage boxes use an IP67-rated perimeter gasket seal that keeps out dust, mud, and rain, plus a pressure-equalization valve that prevents vacuum lock after altitude or temperature changes — so the seal stays tight and the lid still opens at camp.
What size overland cargo box do I need?
Match the box to your loadout: compact cases suit recovery straps and tools, while XL cases and 50 L chest-style boxes hold full recovery kits, camp kitchens, and basecamp gear. Stackable designs let you combine sizes on a roof rack or trailer as your overlanding storage needs grow.
Can I lock an overland box?
Yes. Every Eylar overland box includes TSA-approved locking points, so you can secure your gear at trailheads, campsites, and overnight stops — and still check the case for air travel when the expedition starts at the airport.
