Fabric Fit Tip!

Different fabrics can make a difference in how your suit fits. Check out our fabric guide below to learn more.

Swimsuit Fabrics

  • 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

    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.

  • Ribbed

    True to size

    Another surf inspired fabric, Ribbed has the most stretch of our performance swimsuit fabrics. Ribbed has an extremely soft hand feel.

  • Spacer

    True to size

    Our thickest fabric, Spacer feels almost like a lightweight neoprene wetsuit - making it great for compression and durability.
