The multi-tie Ash top is an easy fan favorite. With a deer print front, a reverse dark brown, creamy white accents, and endless tie variations, this bikini top can be worn however you creatively see fit 🤎

Low-tox isn’t a trend for us—it’s a standard we hold ourselves accountable to.

Most swimwear today is made from synthetic fiber blends like polyester, nylon, and elastane. While built for performance, they come with hidden costs: shedding microplastics during wear/washing which persist in the environment for centuries, and introduce unnecessary chemical exposure to your skin. It’s a lose-lose—for your body and the planet.

The alternative? Amni Soul Eco®—a next-generation polyamide designed to reduce impact without compromising performance. It’s enhanced with a technology that allows biodegradation in anaerobic landfill conditions, meaning that at the end of its life, microorganisms can break it down far faster than traditional synthetics.

Performance is never sacrificed: durability, stretch, shape retention, fast drying, and resistance to salt and chlorine—all intact.
And low-tox goes beyond biodegradability. Our fabric is OEKO-TEX® Standard 100, Class I certified—the highest level. Every component is tested against thousands of harmful substances and verified safe even for sensitive skin.

And unlike brands that rely on vague sustainability claims, we don’t greenwash. We partner with a trusted ethical labor manufacturer in Brazil and choose materials that align with our values. Because doing better isn’t optional—it’s the baseline.

For the wellness-minded, ingredient-conscious, label-reading women out there like me: this is your reminder that what you put on your body matters just as much as what you put in it. And we are here to help upgrade your swimwear game.

All the love,
Maria💌
