All sale items are final sale.
For tops: We do free returns and exchanges on tops that are returned in saleable condition. This means that the colored paper band wrap must be untorn and there is no odor or visible signs of wear. There is a $5 handling and postage fee deducted from your refund. If the item has been worn, it will be eligible for store credit only.
For bottoms: Since we cannot resell or recycle bottoms, bottoms are final sale only. We encourage you to share with someone else in your life if your pair doesn't fit. We also recommend ordering one pair to start rather than a multipack to make sure you like the fit.
We predict you'll love our proprietary Sustainluxe fabric. It's super silky, has great stretch, and keeps you cool and dry.

The secret sauce is in the fabric. Sustainluxe wicks sweat, dries in a snap, and is anti-microbial to keep you fresh.
Undies that multitask.
Never forget to pack a swimsuit again. Minimalist designs and performance fabric means you'll fit in wherever you go. UV and chlorine resistant.

"This brand is a solution to a HUGE need I have when traveling and packing."
I recently took my SOMI’s with me on a 25 day trip around 8 states in the west and was able to go from hiking in them, to hot springing, to lounging, to working, while also being able to wash and care for them with ease on the go. Perfect for my minimal and on the go lifestyle. They dry quickly, feel incredible silky-soft, are comfortable, odor resistant, and are SO CUTE on. -- Kymberly Flores
