Most apparel is designed against a mood board. We design against a spec sheet. The difference shows up early, in patternmaking, and stays visible all the way through to the seam allowances on the final piece.

The spec sheet

For every garment we ship, we lock four numbers before we cut anything:

  • Service life. How many wash cycles before the fabric loses its hand. Targeted, not assumed.
  • Drape coefficient. Measured by hanging a swatch over an edge and photographing it from the side — the curve has to match the silhouette we drew.
  • Seam load. The force a seam must hold without puckering. Different by location: a shoulder is not a hem.
  • Recovery. How fast the fabric returns to flat after compression. Critical for anything that sits in a bag.

Why hardware framing helps

When you treat a jacket like a tool, you stop forgiving it. A zipper is a serviceable component — it should be replaceable. A label is a part number, not a flourish. The lining is a substrate. Reframing the vocabulary forces every choice to justify itself.

This isn’t austerity. It’s how we end up with pieces that survive being worn hard and still look like they were drawn with intention. The aesthetic is downstream of the engineering.

What we’re working on

The next drop is a soft-shell layer drafted against a 200-cycle service life and a drape coefficient we’ve been chasing for six months. We’ll publish the spec sheet alongside it. Type shop from the terminal to see the current catalog while we finish that one.
