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

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