Gear Box 3500



No More Wasting Time Looking For Gear

With the customizable compartments, everything has its place – especially smaller gear that’s always falling to the bottom of plastic bins, such as headlamps, chargers & batteries, first aid, dry goods & snacks, kitchen items, bike essentials, and pet stuff.

Strong Enough to Sit On, Stack Up, or Toss Around

These storage boxes are tough. They’re rigid and can support 100+ lbs of weight on top when the lid is on and the dividers are configured inside for support. All three sizes have a durable abrasion-resistant Cordura outer. We often use ours as chairs, and as a step stool to get in and out of bed.

No More Rattling Sounds While Driving

The quilted sides and dividers dampen sound. Rattling and squeaks drive us crazy while we’re on the road – these storage boxes were carefully engineered to eliminate that.

Adjustable, Customizable, and Easy to Access

Each storage box comes with six movable velcro dividers, and extra divider kits are available for creating smaller or different shaped compartments. The lid is removable – attached on one side by velcro and the other side by a magnetic Fidlock latch. The latch allows you to access your gear quickly and can be opened one-handed. If you don’t want the latch, order the 3500A from the dropdown.

No More Sliding Around in Carpeted Vehicles

Each box has two strips of hook velcro on the bottom, keeping them in place on carpeted surfaces when you’re bouncing around on a washboard road or canyon carving tight turns with no brakes. You can attach loop velcro to the strips if you prefer they slide, or if you’re concerned with them rubbing on your seat material.

Perfect for Under the Sprinter Factory Bench Seat

Two 3500A boxes fit perfectly in the two storage areas beneath the Mercedes Sprinter Crew bench seat. If you prefer the 3500 with the Fidlock latch, we recommend tucking the male end of the latch under the lid before sliding the box under the seat. If you have cup holders, make sure they won't be in the way or they'll need to be removed for the boxes to fit.

Store Anything You Want & Stay Organized

Keep your essential gear organized and protected with the customizable dividers. We won’t judge what you put in your body or your box. If you’re proud of it, send us a photo (or tag us) and we’ll share it so it gets the eyeballs it deserves.

Flat Pack Them When Not in Use to Save Space

The injection-molded corners and lid are removable, allowing you to store the box flat if you’re tight on space.

Three Sizes Available & Where They Are Made

This is the Medium size, with a 35L storage capacity, and it weighs 10lbs. Exterior dimensions (with the handles compressed) are 25.25" wide x 16.75" long x 7.375" tall – in comparison, the 3000 is the Small size (W 18" x L 13.75" x H 12.25") and 5500 is the Large size (W 25.25" x L 16.75" x H 12.25"). The 3500 & 5500 have the same footprint, and the 5500 & 3000 are the same height. They are made in Cambodia.

Leather Handles Make It Comfortable to Carry

Genuine leather handles give the box the finishing touch it deserves and makes it nice to carry, especially when it’s fully loaded.

Easy to Set Up

The boxes arrive flat to your door and are easily assembled by inserting the corners, configuring the velcro dividers and then adding the lid. Watch the assembly video for more details.

External Pockets for Small Items & Quicker Access

If you have things stacked on top of the box and need easy access to small essentials on the road, there are six external pockets that are expandable. Perfect for batteries, camera accessories, tire gauge, snacks, straps & clips, toiletries and more.
