Dirty Gear Bag (fit up to 35 Inch Tire)
Dirty Gear Bag (fit up to 35 Inch Tire)
The 23ZERO Dirty Gear Bag is a 55-liter (14.5-gallon) canvas storage bag that hangs off your spare tire. It's built for the stuff you don't want inside the rig: muddy recovery straps, a wet traction board, soaked boots, a dripping rain shell. The shell is 400gsm poly/cotton canvas with a 1000mm waterproof coating, and the inside is lined in 450gsm PVC, so grime and water stay in the bag instead of soaking into the cab.
It drops over the spare with an adjustable webbing harness and cinches down with 2-inch quick-release buckles — no tools, a couple of minutes. Open dimensions are 27.5 by 22.5 inches with a 5-inch gusset and an 11.5-inch wheel arch, so it fits 32-, 33-, and 35-inch tires up to 12.5 inches wide. Adjustable anti-sag straps keep it from drooping when it's loaded heavy, and a drain eyelet in the bottom lets trapped water run out instead of pooling.
There's an internal zipped dry pocket for the things you want to keep clean — keys, phone, a dry pair of socks — separate from the filth in the main compartment. Hardware is 5mm stainless D-rings, 50mm nylon webbing, and reinforced box stitching on the major seams. When it's full of mud, pop the buckles, pull it off, and hose it out.

Use cases
Built for the dirty-gear shuffle at the end of a hard day: muddy traction boards, wet recovery straps, soaked boots, and dripping layers go on the spare instead of inside the rig. The quick-release harness means you can pull the whole bag to reach your spare or empty it out, and some folks run it as a trail trash bag too.

What tire sizes does it fit?
It's sized for 32-, 33-, and 35-inch tires. The wheel arch is 11.5 inches deep, which clears tires up to 12.5 inches wide. A bigger tire just makes the bag sit a little higher — the 55-liter internal volume stays the same.
How does it mount? Do I need tools?
No tools. The adjustable webbing harness drops over the top of your spare and cinches down with 2-inch quick-release buckles. It's a couple-minute job, and you can pull the whole bag off in seconds to reach the spare or empty it.
Is it waterproof?
It's weather-resistant, not submersible. The shell is 400gsm canvas with a 1000mm waterproof coating, and the inside is lined in 450gsm PVC, so it shrugs off rain and road spray and holds in mud. A drain eyelet in the bottom lets any trapped water run out instead of pooling.
Does it sag when it's loaded?
No. The adjustable anti-sag webbing straps take up slack and keep the bag from drooping even when it's packed heavy with wet recovery gear.
Can I keep dry stuff separate from the muddy stuff?
Yes. There's an internal zipped dry pocket sized for keys, a phone, or a dry pair of socks, so the clean items stay out of the grime in the main compartment.
How do I clean it?
Pop the quick-release buckles, pull the bag off the spare, and hose it out. The PVC liner wipes down and the canvas dries out fast.
