Arriving October 2026.

The Adventure One Piece is back and we made it tougher. Same signature ribbed texture, now in an upgraded fabric built to handle more swimming, more sun and more compliments. 360° medium compression smooths and holds your tummy, while the built-in shelf bra supports A-F cups and the crossover back keeps everything exactly where it should be. Made for swimming, chasing kids, long beach walks and whatever else you get up to when you're not sitting on the sidelines.

• COMPRESSION - Fearless signature 360° compression layer with medium hold through the tummy, without the squeeze
• BUST SUPPORT - built for A-F cups with a built-in shelf bra, larger-bust friendly, with removable foam cups you can wear with or without
• COVERAGE - generous, medium-to-full coverage with a medium-high leg line
• FABRIC - upgraded recycled matte ribbed fabric, built to last 100+ wears
• BACK DESIGN - low, open back with thick elasticated crossover straps for a secure, no-adjust fit
• SIDE PANELS - side coverage panels that lift and shape without adding bulk
• STYLING - doubles as a bodysuit under linen pants, jeans or whatever you throw on after the beach
• SIZE RANGE - XS-3X (Australian sizes 8-20)

The Adventure is for swimming, moving, chasing, walking, lounging and doing it all again tomorrow. One less thing to think about. Exactly how swimwear should be.

Fabric & Care

This swimsuit is made from a luxe, high quality ribbed fabric crafted from recycled plastic bottles and pre consumer waste. Better for the planet, and even better on you.

Outer: 75% recycled nylon, 25% elastane
Lining: 86% polyester, 14% elastane
Power mesh: 85% polyamide, 28% spandex

Sustainability isn’t just about recycled materials - it’s about choosing pieces that last season after season. With the right care, your Fearless swimwear will stay looking incredible for years to come.

Care Tips:
  • Rinse in fresh water after every wear, especially after pools or spas
  • Cold hand wash or gentle cold cycle
  • Avoid tumble drying, bleaching, soaking or ironing
  • Dry in the shade

Then take a well-deserved nap - because laundry is a drag.

FAQs

What cup sizes does the Adventure One Piece support?
Built-in shelf bra and removable foam cups mean it works across A–F cups. Wear the cups in for more shaping, or take them out if you don't need it.

Is the compression firm or light?
Medium hold. It supports your tummy without restricting you, not a firm, shapewear-level squeeze.

What's the coverage like?
Medium-to-full coverage with a medium-high leg line, more coverage than a cheeky cut without going full brief.

What's it made from, and how long will it last?
Recycled matte ribbed fabric in an upgraded, more durable build. Same rib texture you loved, made to last 100+ wears.

Can I wear it as a bodysuit, not just a swimsuit?
Yes. The low, open back and thick cross-over straps mean it works just as well under jeans or linen pants, beyond the beach.

Will the straps dig in or need constant adjusting?
No. They're thick and elasticated, so once it's on there's nothing to adjust.

What sizes does it come in?
XS–3X (Australian sizes 8–20).

The Adventure

A one-piece for the days that actually involve moving. From swimming laps to wrangling kids and beach walks, it highlights the parts of your body you love the most so you don’t have to worry about how your body looks in a swimsuit.

Why You Can Trust Our Sizing

We surveyed 15,000 women before designing a single item and we're still listening.

Every item is fitted and tested on two sizes - a 10/12 (C-Cup) and a 14/16 (E-Cup) - then trialled on real women in their 20s to their 60's. Because no two bodies are the same.

When our fabric ran small, we changed the sizing. Feedback beats data, every time.

Sizes XS-3X. Built for the body you actually have.

Still Not Sure?

Finding a swimsuit that actually sculpts, supports and survives the ocean without a wardrobe malfunction? We used to think that was a myth too. Don't take our word for it - real women are already raving about the fit, the comfort and the "wait, this actually works" confidence Fearless delivers.
