The Le Mont St Michel Simoni Grid Knit Sweater Polo Shirt is a refined summer knit with the shape of a tailored polo and the texture of a lightweight sweater. Its clean collar, three-button placket and tapered hem give it an easy smart-casual feel, making it a versatile piece for warm-weather layering.
Made from 100% cotton, the grid-like waffle knit construction gives the fabric a light, breezy handle with a subtle texture that adds depth without feeling heavy. Ribbed cuffs and hem complete the shape, helping the shirt sit neatly while keeping the overall look relaxed and elegant.

Le Mont Saint Michel is a French heritage brand with roots stretching back to 1913, when brothers Louis and Henri Ariès founded their family workshop in Pontorson, near the borders of Brittany and Normandy. Created to dress the workers, artisans and farmers of the region, the brand became known for robust, practical clothing made for everyday labour. From heavy moleskin jackets and school blouses to corduroy trousers, Le Mont Saint Michel built its reputation on hard-wearing garments with a strong sense of place, purpose and French workwear identity.
Across the decades, the brand became part of the industrial and visual landscape of France, known not only for its durable clothing but also for its bold post-war advertising and regional presence. In 1998, under the direction of Alexandre Milan, Le Mont Saint Michel entered a new chapter, reconnecting with its archives while reworking its workwear heritage for modern life. This balance of tradition and renewal has allowed the brand to retain its authenticity while developing a more contemporary, urban expression.
Today, Le Mont Saint Michel continues to draw from its rich textile history, with a design studio based on the historic Monthorin site in Brittany and collections inspired by generations of family archives. Knitwear, denim and classic workwear shapes are reimagined with a focus on quality, durability and timeless style. Rooted in French craft and shaped by over a century of tradition, Le Mont Saint Michel offers clothing with quiet character: practical, elegant and made to endure beyond passing trends.
