Sustainable Triangle Bikinis for Women Who Live in the Water

Our triangle bikinis are anything but basic. Designed for women who value style, comfort, and performance, these suits combine a flattering, timeless shape with technical features that make them perfect for active days in and around the water.

At Ocean Soul Swimwear, we believe a bikini should do more than just look good. That’s why every women’s triangle bikini in our collection is crafted from luxurious Italian recycled fabric - soft against your skin, resistant to chlorine and salt, and built to last season after season. Plus, with UPF 50+ sun protection, you can soak up the sun safely while enjoying a secure, supportive fit.

Why Choose Our Triangle Bikinis?

Not all triangle bikinis are created equal. While most are designed for lounging, ours are engineered for movement, durability, and comfort — without compromising on style. Here’s what sets them apart:

The classic triangle cut highlights your natural curves, while adjustable ties at the neck and back let you control your coverage and fit.
Double lining and quality construction mean your bikini stays in place, whether you’re diving into the pool or paddling out for a surf.
Made from premium Italian recycled fabric, these bikinis are as kind to the planet as they are to your skin.
Built-in sun protection helps shield your skin from harmful UV rays, letting you enjoy longer days outdoors.
Designed to mix and match with our bikini bottoms, rash vests, and surf shorts for a look that’s uniquely yours.

Sustainable Swimwear, Ethically Made

At Ocean Soul Swimwear, sustainability is more than just a buzzword. Every eco-friendly triangle bikini in this collection is crafted with the planet in mind:

Each suit is made using regenerated nylon from ocean waste, such as discarded fishing nets and fabric scraps.
We produce in small batches to minimise waste and avoid overproduction.
Every bikini is made locally in Bali by skilled artisans who are paid fair wages.

By choosing a sustainable triangle bikini, you’re making a conscious decision to reduce your environmental impact while supporting ethical production practices.

Performance Meets Style

Our triangle bikinis are designed for women who want it all - support, style, and sustainability. They transition seamlessly from the surf to the sand, giving you a bikini top that’s just as comfortable under a wetsuit as it is under the sun.

Tested in real waves to ensure minimal movement and maximum comfort.
Ideal for both saltwater and poolside wear, retaining its shape and colour over time.
Perfect for all-day wear, so you can go from water to café without feeling damp or uncomfortable.

Beautiful and flattering

There’s something about the ocean. Maybe it’s the rhythm. The way it mirrors your breath. Or the way it invites you to let go—of stress, of tension, of everything you thought you needed to carry.

Why Surf Swimsuits Make All the Difference in and out of the Water

If you’ve ever been out on the waves, you know that the right gear can make or break your surfing experience. While choosing the right surfboard or wetsuit is crucial, the importance of selecting the best swimsuit for surfing should not be overlooked.
