Is the SF821 chlorine-proof?

Yes — the SF821 is made from chlorine-resistant Italian Carvico XLANCE fabric, designed to keep its fit and colour even with frequent pool use.

What’s the difference between SF821 and SF811?

The SF811 is slightly shorter in body length with a lower neckline. The SF821 gives more torso length and coverage, with the same secure X-back design.

How do I choose the right size?

Check the size chart above. If you’re between sizes, go up for more torso room. We also recommend looking at our customer photos to see real fit examples.

Is the fabric eco-friendly?

Yes — SF821 uses recycled fibres in its Carvico XLANCE fabric, making it both performance-driven and sustainable.

How should I care for my swimsuit?

Rinse immediately after use, wash gently with mild detergent, and line dry in the shade. Avoid wringing, tumble drying, and bleach.
