A modern performance essential designed with a sleek, sculpted silhouette. The JUSTWATCH Women’s Trackline Halter Bra combines a fitted cropped shape, high halter-inspired neckline, and contrast binding for a clean, elevated athletic look.

Made from a lightweight 80% polyester, 20% elastane performance blend, the smooth knit fabric provides comfortable stretch and flexibility while maintaining a close-to-body fit. Seamless shoulder construction creates a streamlined finish and allows natural movement through the upper body.

Pair it with the JUSTWATCH Women’s Trackline Leggings for the complete matching set, or style it with your favorite JUSTWATCH bottoms for Pilates, yoga, training, travel, and everyday wear.
