Sizing Guide


Sizing Guide: OKAICOS swim trunks are made from performance stretch material, providing an athletic, tailored slim fit. The waistband does not stretch. We recommend sizing up if you are between sizes as you can tighten with the drawstring. If you have sizing questions, please reach out to info@okaicos.com. We can help.
