Good to know about Hiroshi Kato sizing
- Take your usual size. If you wear a 32, buy the 32.
- Their waistband figure is measured flat, so double it. Each pair runs about 2" above the tag.
- Raw denim stretches, so the best first fit is snug.
These are Hiroshi Kato’s own measurements, published as-is. Stuck between sizes? Message us and we’ll get you into the right size.

Description
The Pen is Kato's slim fit and the one they sell the most of. Medium rise, slim through the thigh and leg without going skinny — 16¼" at the knee to a 14" opening — with 4-way stretch so it moves. Kato pitches it for average builds wanting a tailored look. Made in the USA; the fabric weight changes with the wash, the cut doesn't.
Pick a wash above. Every Pen is cut the same; only the fabric and color change.
Fit specs (Kato's garment measurements, size 32)
- Front rise: 10"
- Thigh: 23½"
- Knee: 16¼"
- Leg opening: 14"
- Inseam: 34" (unhemmed)
- Compared to the rest: the slimmest Kato we carry — 2" narrower at the hem than the Hammer
Raw denim stretches with wear — Kato says buy your usual size and expect the first fit to be snug.
