Le Mont St Michel Thurin – Breton Striped Shirt – Navy / Offwhite

Le Mont St Michel Thurin – Breton Striped Shirt – Navy / Offwhite

A maritime classic from a French heritage brand established in 1913.

Some garments never go out of style. The traditional Breton striped shirt, known in France as the marinière, is one of them. The Le Mont St Michel Thurin continues the tradition of a style embraced by cultural icons from Pablo Picasso to John Wayne, celebrating a distinctive part of French maritime heritage.

In this Navy / Offwhite colourway, navy forms the dominant shade, contrasted with offwhite horizontal stripes. The darker palette gives this maritime essential an understated character, equally at home with raw denim or classic chinos.

Traditional French Knitted Cotton

Crafted from 100% cotton jersey knitted in France using traditional techniques, the Thurin has a substantial, tightly knitted construction. Its textured fabric combines comfort, durability and structure, reflecting the practical spirit of authentic maritime clothing.

The finished garment is manufactured in Portugal, bringing French textile heritage together with European garment-making expertise.

Classic Maritime Design & Fit

Faithful to the classic codes of the marinière in both its cut and its spirit, the Thurin features a slightly widened boat neckline, long sleeves and a traditional straight silhouette. Its comfortable shape makes it a versatile piece to wear on its own or layered beneath a French chore jacket.
