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 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

Why Choose Eylar Overlanding Cases for Off-Road Adventures
When the trail gets rough, your overlanding cases and overland storage cases need to perform at the same level as your rig.

Here's how our cases stack up:
| Feature | Aluminum SM Series | Roto-Molded SR / SRX Series |
|---|---|---|
| Shell Construction | Heavy-gauge aluminum | Roto-molded polymer |
| Weatherproofing | Perimeter gasket seal | Perimeter gasket seal |
| Pressure Equalization | Valve included | Valve included |
| Stackable Design | Yes — vertical & horizontal | Yes — modular stacking |
| TSA-Approved Locking Points | Yes | Yes |
| Foam Insert Option | Pluck-and-pull customizable | Pluck-and-pull customizable |
| Rack / Bed Mount Ready | Yes | Yes |
Whether you're building a rugged storage box system for a truck bed, roof rack, or trailer bay, both series deliver expedition-grade overland storage cases and genuine overlanding storage capacity without compromise.
Eylar Overland Cases & Cargo Cases — Built for Off-Road Adventures
Every Eylar overland case in this collection is engineered for the trail: kitchen setups, recovery gear, multi-day food and water storage, basecamp tool inventory, or bug-out loadouts. Our overland cases and cargo cases include aluminum cases for corrosion-resistant heavy-duty storage, low-profile rack cases for clean roof-rack mounting, and roto-molded crossover cases for the toughest overlanding case needs. Whether you call it an overland box, an overland cargo box, or an offroad storage box, these are purpose-built rugged storage cases for serious expeditions.
Overland Storage Boxes — SM Series
The SM series of overland storage boxes (30L, 50L, 95L) is the classic aluminum overland cargo box: heavy-gauge aluminum construction, weatherproof gasket, integrated lockable points. Stack vertically in truck beds, mount to roof racks, or lash to trailer bays. The SM overlanding storage box is the workhorse standard for serious overlanders seeking dependable overland gear boxes and hard case storage on every expedition.
SR & SRX Series — Off-Road Crossover Overlanding Cases
The SR (90L, 110L) and SRX (50L, 90L, 110L, 175L) overlanding cases combine aluminum-grade durability with roto-molded shells. Sized for daily expedition kits, week-long basecamp builds, and full-family overland trips. Stackable design delivers modular overland storage cases and cargo systems for any rig.
Low-Profile Rack-Mount Overland Cases
The 38", 44", 48", and 53" Eylar Auto-series overland cases are engineered to mount cleanly on roof racks, truck bed slats, and trailer bays. Slim profile minimizes wind drag at highway speeds and clears low garage doors and trailheads that taller overland cargo box options can't. A top choice for those building a clean rack-mounted overland storage box system and the go-to offroad storage box for roof-rack builds.
Aluminum vs. Plastic — Off-Road Reality
Plastic cargo cases flex under heavy load, crack under UV exposure, and warp in desert heat. Eylar aluminum overland storage boxes and roto-molded overlanding cases are built to absorb the vibration, impact, and temperature extremes that real off-road travel delivers. If you need a rugged storage box that outlasts the trail, aluminum and roto-molded construction are the only credible answers.
Frequently Asked Questions — Overland Storage Boxes & Off-Road Cases
What is an overland cargo box?
An overland cargo box is a hard-sided, weatherproof storage case designed to mount on a vehicle roof rack, truck bed, or trailer for off-road and overlanding use. Eylar overland cargo boxes feature aluminum or roto-molded construction, perimeter gasket seals, and TSA-approved locking points for secure expedition storage.
Are Eylar overland storage boxes weatherproof?
Yes. Every Eylar overland storage box ships with a perimeter gasket seal that blocks dust, mud, and rain. A built-in pressure-equalization valve prevents vacuum lock caused by altitude changes or temperature swings, keeping your gear protected across all conditions.
Can I mount an Eylar overland box on a roof rack or truck bed?
Yes. Eylar overland box cases are designed for roof-rack and truck-bed mounting. The SM aluminum series stacks vertically or horizontally in bed slats, while the low-profile Auto-series mounts cleanly on rack systems to minimize wind drag. Both are purpose-built rugged storage box solutions for vehicle-based overlanding.
What makes a rugged storage box suitable for off-road use?
A genuine rugged storage box for off-road use needs a hard shell (aluminum or roto-molded), a weatherproof gasket, a pressure-equalization valve, and secure locking points. Eylar offroad storage box cases meet all four criteria and add customizable pluck-and-pull foam inserts for gear-specific protection on any expedition.
Are Eylar overlanding storage boxes stackable?
Yes. Eylar overlanding storage cases are built with stackable geometry so you can run multiple boxes on a roof rack or in a truck bed without shifting or rattling. The SM, SR, and SRX series all support stacked configurations, making it easy to build a modular overland storage cases system scaled to your rig.
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.
