Navy blue works like black, but is better suited for high temperatures. It's dark enough to look neat, but less formal than black. It goes with white, grey, beige, light jeans — without having to think.
The Marzamemi is the Essential version: 170-gram combed cotton, light and breathable, designed for everyday use in spring and summer. The lightness of the fabric is its strong point: it doesn't weigh you down, it doesn't retain heat.
Muscle fit cut: snug on the shoulders and chest, with more room around the abdomen. Combed cotton keeps the navy blue uniform over time — it doesn't tend to green or grey after washing.
