Size Guide

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!

FINAL SALE

Step aside swim practice - onesies aren't just for the pool deck anymore. 

Meet the Steve. Our original beach onesie with a cheeky fit, a low-slung tie-back, and a lot of personality. Features clean finish silhouette and a deep v-neck. 

Our 2.0 edition of the Steve comes with added front torso length and a more fitted leg opening for security.

Unlike our training one-pieces, the Steve 2 comes in XS - XL sizing. The relaxed fit is designed to more easily fit across sizes and is created with beach adventuring, not training, in mind.
