Micro Ondes is a proprietary finish Sellam developed for the 69 sub-line: GOTS-certified organic cotton pushed through a dimensional-wave treatment that leaves the fabric with a low corrugated topography. On white, the ripple reads as shadow-and-highlight across the body of the tee, the surface never flat. A narrow leather spine insert runs the back; the Steel Staple 69 agrafe marks the neckline. The cold-dye process after construction lets the pigment settle differently at the ripple peaks versus the ripple troughs - a faint tonal difference that deepens with laundering. The tee softens with each wash, but the Micro Ondes texture holds.
