Unisex Mason Shirt "Sibbjans"

A timeless unisex denim shirt designed for everyday wear, season after season. Cut from a lightweight denim fabric with a soft hand feel, this shirt balances structure and ease — equally at home worn on its own or layered.

The minimalist silhouette is defined by a clean band collar, subtle button placket, and gently curved hem. Carefully considered proportions give it a relaxed yet refined fit that works across styles and genders.

Made to age beautifully, the fabric develops character over time while remaining breathable and comfortable throughout the day — from city mornings to slower coastal evenings.
