Boston, Massachusetts · Barcelona, Spain — Founded 2025
OUR STORY.
Created with intention. Made to stand apart.
Our Story
Founded in 2025, HASHASHIN is an independent luxury clothing brand built around a simple belief: exceptional clothing begins with exceptional attention to detail.
Founded by a veteran and shaped between Boston, Massachusetts, and Barcelona, Spain, the brand draws from a background of discipline and craftsmanship while remaining firmly rooted in contemporary fashion.
Each garment is thoughtfully designed and produced using premium materials, substantial fabrics, rich garment dyes, and carefully considered construction. We focus on the details that define how a piece looks, feels, and wears — creating garments designed to become lasting parts of your wardrobe.
Our collections are released in strictly limited quantities. Each drop is produced in a predetermined run, and once that run is complete, it will not be reproduced. No artificial scarcity. No unnecessary excess. Just considered design, exceptional garments, and collections made to stand on their own.
Community
More Than Clothing
A customer chose to make HASHASHIN permanent — tattooing our logo on his leg. No campaign. No incentive. Just a genuine connection to the brand. That kind of loyalty can’t be manufactured.
A Foundation of Purpose
HASHASHIN was founded by a veteran, but the brand is defined by what we create. Our approach is rooted in an appreciation for quality, thoughtful design, and the details that make a garment worth keeping. From the fabrics we select to the way each piece is constructed, we focus on creating clothing that feels considered, distinctive, and lasting. The product speaks for itself.
Premium Materials
We believe exceptional garments begin with exceptional materials. Every fabric is carefully selected for its texture, structure, feel, and longevity, chosen not simply for how it looks, but for how it performs and develops over time. From the first touch to years of wear, our materials are chosen to deliver a level of quality and refinement you can feel. Nothing is selected without purpose.
Made with Care
Every HASHASHIN garment is developed entirely from scratch. Each piece begins as an original design by Devan Dupuis, translated into detailed tech packs that guide every stage of development. We work directly with our manufacturing partners, personally selecting and evaluating materials and traveling to the factory to oversee sample development, refinement, and quality control before production begins. We believe exceptional clothing requires more than a design on paper. It requires being there to see, feel, refine, and approve the finished piece. From embroidery and debossing to specialty dye processes and other techniques, we continually explore new ways to elevate our garments and develop a distinct design language. Every piece is considered from the first thread to the final stitch.
Signature Style
The HASHASHIN leopard is a defining signature of the house — an emblem that has become inseparable from our visual identity. Applied through refined embroidery, considered graphic treatments, and distinctive finishing techniques, the leopard is integrated into each collection with the same attention to detail as the garments themselves. Its presence is deliberate: recognizable without being overstated, and designed to remain distinctive across every collection.
Lasting Color
Color is an integral part of the design. We use carefully selected garment dyes chosen for their rich, lasting color and skin-conscious composition. Developed with consideration for both the garment and the wearer, our dyeing processes create deep, dimensional tones while maintaining a comfortable finish against the skin. The result is color with depth and character — designed to remain beautiful through continued wear.
Devan Dupuis
Founder
Devan Dupuis founded HASHASHIN near Boston, Massachusetts, in 2025, bringing together a lifelong appreciation for design, culture, and the details that make exceptional clothing distinctive.
His perspective has been shaped by an extensive creative background spanning fashion, photography, music, film, and work alongside artists and recognized creative talent. Years of travel and exposure to different cultures, aesthetics, and ways of life have further informed his approach to design, creating a point of view that is both personal and international.
Today, the brand operates between Boston and Barcelona, with its collections available internationally. Each piece reflects that broader perspective — considered in its proportions, materials, color, construction, and overall character.
Devan’s military service is one part of his personal history, contributing to the determination and standards he brings to his work, but the identity of the brand extends far beyond it.
HASHASHIN is an expression of a life spent experiencing different places, people, and creative disciplines, distilled into clothing designed with intention and lasting character.
