True luxury is born at the origin — where exceptional materials meet refined technique.
We select the finest natural raw materials, ensuring superior comfort and enhanced performance form the foundation of every garment.
From there, meticulous craftsmanship and signature techniques elevate each piece, turning thoughtful design to enduring style, made to last for generations.
Merino Wool
Offering next-to-skin softness with a subtle, natural shine, our Merino wool shorn from the sheep of Australia is 100% natural and renewable. Inherently breathable, it is warm without the weight yet cool when needed. With innate moisture-wicking, comfort, and stretch with shape recovery, its versatility elevates apparel across luxury to performance wear.
Giza Cotton
Grown in the rich soil and unique climate of the Nile Delta, Giza cotton is among the highest-grade cottons in the world. Known for its natural sheen and strength, with uniform, smooth fibers that resist pilling and enhance durability, it delivers a silky finish with breathable comfort for long-lasting luxury.
Mongolian Cashmere
Combed from the undercoats of goats raised on the steppes of Mongolia, our cashmere offers an exceptional butter-soft feel and elegant drape. These ultra-fine fibers provide lightweight insulation and natural breathability, with unmatched warmth-to-weight. Ethically and sustainability combed by shepherds to preserve the integrity of both animal and fiber, Mongolian cashmere offers enduring luxury.
Proprietary Knits
Innovation is knit into the very fabric of Saint Croix. Every knit is designed and crafted in-house in our mill in Winona, MN, where traditional craftsmanship meets modern innovation to create signature fabrics not found anywhere else. Through advanced techniques we have developed knits with a polished feel, designed superstretch fabrics with exceptional shape retention, and refined naturally warm wool to be exceptionally lightweight and cooling when needed. Across luxury to the everyday and performance, our techniques enhance comfort, elevate structure, and ensure garments will last a lifetime.
Intentional Microfiber Blends
Dedicated to the art of craftsmanship with fine materials, Saint Croix elevates the selective use of microfiber through deliberate design and material mastery. Our proprietary process seamlessly blends natural wool and cotton fibers with microfibers, resulting in a refined, stable, lightweight knit. Engineered for exceptional breathability, moisture-wicking capabilities, shape retention, and rich color preservation, this specialized knit is thoughtfully applied to select garments for enhanced performance and long-lasting comfort.
Hand-Looped Seams
Committed to the highest standards of quality and comfort, Saint Croix preserves the time-honored technique of hand-looping — a meticulous, labor-intensive process largely abandoned in modern knitwear. Individual stitches are joined by hand, creating a smooth, seamless structure that maintains the natural stretch and drape of the knit. Applied across necklines, sleeves, hems, and socks, this rare craftsmanship ensures a superior fit, refined comfort, and an elevated finish.
Custom Collars
For luxury with longevity, Saint Croix custom collar innovations ensure enduring shape and comfort across our garments. Saint Croix polos are designed with a seamless, knit-in collar stay that prevents rolling or curling, maintaining a crisp edge that lasts through repeated wear and care. Quarter-zip sweaters feature an engineered collar that gently drapes away from the neck, offering a clean, refined shape that holds its form. V-neck collars are crafted without an interior seam at the v-neck point, knit to size and hand-looped to lay flat for seamless, lasting comfort. Every Saint Croix collar is crafted with the philosophy that true refinement lies in what holds its shape.
