The collection
Every shirt is numbered and made in a single run. Choose one to see its cloth, weight and sizes.
The cloth comes first
A T-shirt has nowhere to hide. Three decisions make the difference, and each one shows after a year of wear.
Long-staple cotton
Sea Island and Supima fibres are longer than ordinary cotton, so the yarn spins finer and pills less. The hand feel improves with washing.
A cut for the shoulder
The seam sits on the point of the shoulder. The sleeve ends mid-bicep. The body falls straight, with 4 cm of extra length at the hem.
Finished by hand
Neck ribs are set with a flat seam that won't bow. Henley plackets carry real mother-of-pearl buttons, sewn with a shank.
