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
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.
