Choose CX79 boy-leg swim briefs for sporty short-leg coverage and a close, stable fit, rather than a high-cut swim brief or longer trunk.

What makes the fabric unique?

Smooth, stretchy Italian swim fabrics provide a close, supportive fit that moves comfortably in the water. Selected styles use chlorine-resistant Extra Life Lycra® for improved shape retention; finishes and performance vary by style.

How do I find my size?

Measure your low waist and follow the chart. Swim fabric stretches less; choose the larger size if between sizes.

Which pouch should I choose?

This CX79 style features Contour for a close, secure and movement-friendly fit.

How should I care for this collection?

For all swim styles, rinse immediately after pool or sea use, hand-wash cold with no harsh detergents or bleach, and air-dry in the shade. Check each garment label.

To help preserve the quality of your garment, we recommend turning it inside out or placing it in a wash bag before laundering to avoid friction with abrasive surfaces.

Use a gentle cycle or hand wash in cold to warm water, and opt for a mild liquid detergent, ideally eco-friendly as it's gentler on fibres. We also suggest line drying in the shade to maintain the fabric's integrity.
