1680D ballistic weave. Custom hardware. Built to outlast the gear inside it.

Most gym bags use 600D polyester. Ours is 1680D ballistic weave — the fabric grade used in high-end luggage — because a bag that gets thrown in a trunk six days a week takes more abuse than a suitcase ever will.

The zippers and hardware are custom stainless steel, tooled for this bag specifically. Hardware is the first thing to fail on a cheap duffel, and it's the part most brands don't bother to change.

Every piece of your kit has a place:

  • Hidden shoe compartment — folds out when you need it, tucks away when you don't. You never lose the space.
  • External belt holder — keeps your belt flat on stainless clips instead of bent around everything else.
  • Waterproof wet bag — sweaty clothes sealed off from clean ones.
  • Removable dividers — your shaker stops rolling around with your chalk.
  • Three zip pockets, two mesh pockets — small things stay findable.

Works after the gym, too

Laptop sleeve, luggage sleeve, and a hidden travel pocket. It handles the office and the airport as well as the gym floor.

The details:

  • 40L — 21″ × 10″ × 12″
  • 1680D ballistic weave polyester
  • Custom stainless steel zippers and hardware

  • Padded shoulder strap + reinforced handles
