If you’ve ever wished your favorite gear box was just a little more travel-friendly, say, compact enough to slide under a truck drawer or fit into a van build without sacrificing durability, RUX just answered that wish.

The new RUX 40L Gear Box is the latest addition to RUX’s modular storage ecosystem, bringing the same waterproof construction, carry versatility, and smart features of the RUX 70L (reviewed here), but in a more compact form factor.

At 40 liters, this one’s designed to go places the bigger box can’t, making it a serious contender for road trips, overlanding, camp kitchens, and even air travel.

What is the RUX 40L Gear Box?

Like its larger sibling, the RUX 40L is a hybrid between a rugged tote and a high-end duffel bag.

It’s waterproof, dustproof, collapsible, and built for serious use, just in a shorter silhouette that’s easier to stash and carry.

At just 5.7 lbs, it’s light enough to travel with and collapses down to under 3 inches tall when empty. That means you can slide it under a seat, into a drawer, or stash a spare in your van without taking up valuable real estate.

Whether you’re organizing gear in a Sprinter van, hauling essentials to a backcountry basecamp, or replacing the chaos of traditional duffel bags with something far more orderly, the 40L is built to simplify how you move.

Press Seal Lid

Unlike your average tote, the new Press Seal Lid snaps closed with a watertight seal, offering real protection from the elements, without the fuss of roll tops or zippers. It’s ideal for quick access on the go.

Comfortable carry

The upgraded padded straps have a silicone backing for grip and comfort. You can use them backpack-style, over-the-shoulder, or just grab the handles and go.

Modular compatibility

It plays perfectly with the rest of the RUX modular system, including packing cubes, short organizer panels, and RUX lash accessories.

It’s slatwall and L-track compatible, too making it ideal for garages, boats, and vans.

Built for real use

From ATV racks and boat decks to overhead bins and under-bench storage, the 40L was purpose-built for environments where size matters but durability can’t be compromised.

How the 40L compares to the 70L

Best ForTravel, compact kitsBig haul missions, basecamp gear, garage storage

So while the 70L still reigns supreme for full-blown expeditions or garage gear storage, the RUX 40L is better suited to travel, daily use, or smaller vehicles, especially when every inch of space matters.

Who is the RUX 40L for?

  • Vanlifers and overlanders needing modular gear that fits tight spaces
  • Campers wanting a camp kitchen kit or recovery box that’s organized and waterproof
  • Boaters and off-roaders looking for strap-down-ready storage
  • Frequent travelers who want to ditch the soft duffels for something more durable and protective
  • Anyone who loved the RUX 70L, but found it too big for certain scenarios

Final thoughts

RUX calls the 40L Gear Box their “half-height hauler,” but there’s nothing half-measure about it.

It’s a highly considered addition to the RUX lineup, designed for people who pack with purpose and want their storage to be as tough, adaptable, and beautiful as the adventures they’re heading out for.

If you’re the kind of person who gets joy out of a clean, modular gear setup, you’ll probably want one of these in your rotation.
