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. Browse our dedicated aluminum overlanding cases → if you need a metal-shell-only build.
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 at low temperatures, and degrade under UV. Aluminum overlanding cases hold geometry under stacking pressure, survive years of sun and salt-air exposure, and shrug off river crossings without warping — making them the gold standard among rugged storage cases and hard case storage solutions for off-road use.
Stackable, Lockable, Modular Overland Storage Cases
Stack vertically in roof racks, truck beds, or trailer bays. Integrated locking points keep your kit secure at trailheads, campsites, and overnight stops. Build a complete overlanding storage system from modular Eylar overland cases that interlock and lock down — the most versatile overland gear boxes available for any overlanding build.
Overland Gear Boxes: Built for Every Expedition
Not sure which overland storage box fits your build? Here's what matters most when choosing overland gear boxes for serious trail use:
- Weatherproofing: Every Eylar overland box in this collection features a weatherproof perimeter gasket that keeps dust, mud, and rain out of your gear — essential for multi-day overland storage cases exposed to the elements.
- Stackability: The SM, SR, and SRX series are designed with flat, interlocking lids so you can stack multiple overland cargo boxes vertically in a truck bed or trailer bay without shifting on rough terrain.
- Roof-rack compatibility: The low-profile Auto-series offroad storage box lineup is purpose-engineered for rack mounting — slim enough to clear height restrictions while delivering full cargo cases capacity on the trail.
- Overland storage boxes vs. soft bags: Soft bags compress, soak through, and offer zero crush resistance. A dedicated overlanding storage box protects sensitive gear — electronics, medical kits, optics — that can't afford moisture or impact damage on rough terrain.
