Asymmetric Power. High-Speed Drying. Professional Sculpting.
Break the mold of traditional activewear with the One-Shoulder Series.
Designed for the modern woman who balances intensity with elegance, this sports bra offers a sophisticated asymmetric silhouette that doesn't compromise on stability. Whether you are holding a complex yoga pose or hitting your peak pace on the treadmill, this vest-style top provides a high-security fit with a high-fashion edge.
The bold one-shoulder design is engineered with a wide, reinforced strap to ensure even weight distribution and a secure, "stay-put" fit during dynamic movement.
Built for high-performance athletes, the specialized quick-drying fabric accelerates evaporation, preventing that heavy, damp feeling even during the most grueling cardio or hot yoga sessions.
The extended under-bust construction provides extra coverage and stability, allowing this piece to function perfectly as a standalone gym top or a supportive base layer. Advanced knitting technology creates a smooth, friction-free surface that glides against your skin, eliminating irritation during long-distance runs or repetitive gym movements.
The minimalist, solid-color design makes it an effortless match for high-waisted leggings, shorts, or even layered under a streetwear jacket for a post-workout look. Premium Fabric Composition A luxury performance blend designed for maximum elasticity and a silky touch: 80% Nylon: Provides exceptional durability, high-definition color retention, and a smooth, cool-to-the-touch sensation.
20% Spandex: Delivers superior 4-way stretch, ensuring the bra moves with your body and snaps back to its original shape after every wash.
Size & Fit Tip: We highly recommend checking our Size Guide before purchasing. Pro Tip: If you find yourself between two sizes, we suggest choosing the larger size to ensure perfect comfort and the most flattering fit on your body.
