Fortis Range full collection

The foundation of Robore Mentis.

The Fortis Range is where it all began—our launch design and a lasting symbol of strength, resilience, and purpose. Inspired by our Royal Marine roots, this collection set the tone for everything we stand for: quality, discipline, and understated style.

Crafted in Portugal from premium 100% organic cotton, every piece delivers clean lines, everyday versatility, and enduring comfort. Built with intention. Worn with pride.

This is legacy, stitched into every thread.
