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.
-
Recycled Sea-Flex
True to size
Made of recycled fishing nets and other discarded nylon, Recycled Sea-Flex is a chlorine resistant performance fabric with the perfect blend of lifestyle comfort and athletic support. It has a soft hand feel and 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.
