Engineering
Every detail carries its weight.
We stripped the ARMB001 down to what matters and over-built each part. Look closely — the value is in the millimetres.
F—01
Sealed against the weather
A DWR-treated 840D ballistic shell beads water on contact, backed by AquaGuard® zippers that keep the interior dry through a downpour.
F—02
Hardware built to outlast you
Anodized alloy G-hooks and injection-molded buckles are rated to 40 kg of pull each. Nothing plastic, nothing that rattles.
F—03
Load that disappears
An HDPE framesheet transfers weight to the hips while die-cut foam floats against your back. 28 litres that carries like half of it.
Technical sheet
The full spec.
No marketing rounding. These are the exact figures we build and test to, measured on the production line in Da Nang.

“Two years of daily abuse across four continents. The zippers still glide like day one. This is the last bag I will buy.”

“The restraint is the point. No logos screaming, no wasted stitch. It reads as expensive because everything about it is deliberate.”

“Dumped a full water bottle inside my rain cover and my laptop stayed bone dry. The framesheet makes 12kg feel like nothing.”

Before you commit.
Yes. At 52 × 32 × 20 cm it fits within the cabin allowance of every major carrier, and the compression straps cinch it smaller when packed light.
The shell and AquaGuard® zippers handle sustained rain and splashes. For full submersion we include a roll-top rain cover in the top pocket.
Every seam, zipper, buckle, and panel — against manufacturing defects, for as long as the bag exists. Warranty transfers with resale.
