A sport-ready one-piece swimsuit built for performance and style

The One-Piece Sport Swimsuit by Cooper & Hayes is a women's active swimwear essential designed for those who refuse to compromise between function and fashion. With a sleek silhouette and eye-catching details, it moves confidently from lap swimming to beach days.

Why You'll Love This Swimsuit

  • Back cutout design — Adds a modern, fashion-forward detail while maintaining a secure, supportive fit.
  • Decorative stripe accents — Create a sporty, streamlined look that stands out in and out of the water.
  • Round neckline with integrated brief — Delivers comfortable, reliable coverage so you can move freely without adjusting.
  • Quick-drying construction — Lightweight, fast-drying fabric means less time waiting and more time enjoying.
  • Ombre gradient colorways — Expressive, vibrant options that bring a fresh energy to your swim wardrobe.

Perfect for active pool sessions or a relaxed day by the shore, this swimsuit pairs beautifully with a wide-brim hat and sandals for an effortlessly put-together warm-weather look.
