A little sizing tip!
For suits in our Foreverever fabric - if you are in between sizes, or really close to another size, we recommend you size up. For example, if you usually wear a small or medium, you will most likely be a medium in Foreverever fabric products.

For Recycled Sea-Flex fabric products, we recommend you stick to your usual size.

Swimsuit Fabrics

  • Foreverever fabric

    Foreverever

    Consider sizing up

    Our classic Foreverever® fabric is loved by athletes for its durability. By design, it has the least stretch and is the most structured of our fabrics, so if you're in between sizes or prefer a more relaxed fit, we recommend sizing up from your usual size in other brands.

  • Sea-Flex performance swimwear fabric icon

    Sea-Flex

    True to size

    Created with surf in mind, Sea-Flex is high quality performance fabric with the comfortable feel of lifestyle swimwear. It has a bit more stretch than Foreverever.
