Obsidian Zea Thick Side Bottoms

Confidence begins with comfort.

The most luxurious swimwear isn't the piece you constantly adjust—it's the one you forget you're wearing.

The Obsidian Zea Thick Side Bottoms are designed with wider side bands that sit comfortably against the body, creating a flattering silhouette with a secure, effortless fit. The result is a bikini bottom that moves with you, stays in place, and feels as beautiful as it looks.

Minimal in design and timeless in black, Zea is made for long beach days, slow afternoons by the pool, and every destination in between.

Because true confidence comes from feeling completely comfortable in your own skin.

Crafted with intention.

Every Obsidian piece is handcrafted in South Australia using premium double-lined recycled swim fabric selected for its buttery-soft feel, supportive stretch and exceptional durability. Each bikini is created in intentionally limited quantities—not mass produced—so every piece feels considered, exclusive and made to last.

Luxury isn't about owning more.

It's about choosing pieces you'll wear again and again.
