product details
  • designed in USA, made in China
  • patent-pending
  • LATEX INFO: we cannot guarantee that the inner grip strip of our suits is entirely free of latex. If you have a latex sensitivity or allergy, we recommend exercising the same caution you would typically use when assessing whether to wear a product that may contain latex.

  • hand wash only, lay flat to dry
swimsuit care
  • Hand wash in cold water as soon as you can after use (rinsing in the shower is fine!)
  • DO NOT machine wash.
  • Lay flat to dry, do not hang.
  • Do not dry clean, iron, or machine dry (even on a delicate cycle...) as this can, and most likely will, damage your onewith.
  • Hot tubs and chlorinated pools with harsh chemicals can impact the quality and longevity of any swimwear, so it’s best to avoid them if you want to keep your swim in tip-top shape.
  • If you wear your onewith under normal clothes, keep in mind that friction can create pilling/snagging. We prefer to wear our onewith under beach cover-ups/sarongs, which are created to be worn with swim.
  • Sunless tanners, suntan lotions, oils, and harsh chemicals can ruin your onewith - ensure to not get these products in contact with any swim/garments!
