The Return Collection
Built to Hold the Line.
Arc Core is built for pressure — and this sports bra is no exception.
Designed with compression fabric, a double-layered front, and reinforced shoulder straps, this bra delivers dependable support through running, jumping, and heavy training. The longline silhouette provides added coverage and stability, making it equally effective as a workout top or a clean streetwear layer on rest days.
All black. No noise. No compromise.
