Exclusive to FITZ. Designed to lead, not follow.


The FITZ Long Sleeve Obsidian Set redefines what performance activewear looks and feels like. Designed as a statement piece, this set blends sculpting technology with refined elegance — creating a silhouette that is powerful, confident, and unmistakably FITZ.


Crafted from advanced contouring fabric, the leggings are engineered to sculpt and enhance your natural shape. A ribbed high-waist waistband provides firm yet comfortable core support, cinching the waist while maintaining a smooth, seamless finish. The hidden bum scrunch works subtly to lift and shape the glutes, while strategic ribbed detailing around the lower glutes and thighs enhances definition and creates a strong, athletic physique from every angle.


The long sleeve crop top sets this design apart. Featuring a flattering scoop neckline and open-back silhouette, it balances strength with femininity — offering support where you need it, and freedom where you want it. Designed to contour the upper body while allowing full range of movement, it delivers a confident, elevated look that transitions effortlessly from training to lifestyle wear.


This is not a trend piece.

This is innovation, confidence, and design — introduced to the UK by FITZ.
