Supplex
is a longtime favorite in the Splits59 collection. It is our most substantial performance fabric, offering a supportive fit, lasting durability, and a smooth, flattering finish. Designed to hold its shape through workouts, travel, and everyday wear, it's the fabric behind some of our most iconic silhouettes, including the bestselling Raquel Flare. With its perfect balance of comfort, structure, and timeless appeal, Supplex remains a go-to season after season.
