A swim top that provides medium compression, anti-chafe construction, and athletic support — built to perform in the water the same way the Boss Flex performs in the gym.

  • Medium compression — holds securely in water without restricting breathing or movement
  • Chlorine-resistant recycled fabric — holds shape and color through the full swim season
  • Anti-chafe internal seam construction — seams face away from skin; no irritation during lap swimming
  • Brushed underband elastic — soft napped finish; doesn't abrade when wet
  • Sweat and water-wicking lining — manages moisture in and out of the water
  • Athletic silhouette — performance-first design; appropriate for lap swimming and water sports
  • Quick-dry — comfortable minutes after leaving the water
  • Size-inclusive — XS to 4XL

    Nice material. Cup sizes need to be larger. The width of band is good but cup coverage rather small for larger breast.

    Wasn't meant to be

    I thought I ordered the correct size for myself, but it turned out to be comically small. The returns process was easy and I will stick with underwear only from now on.

    I recommend reaching out to customer service before ordering if you're unsure about sizing.
