One Pieces
Torso measurement is most important for finding your accurate one piece size.
If you are in between torso measurements or know your torso runs long we recommend sizing up!

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.
