What Does UPF50+ Swimwear Actually Mean?

Not all swimwear protects you from the sun. And if you’ve ever assumed it does… you’re not alone.

What Is UPF?

UPF stands for Ultraviolet Protection Factor. UPF50+ means the fabric blocks 98% of harmful UV rays. Unlike sunscreen, it doesn't wash off. 

Why Fabric Matters

Cheap swimwear:

  • Stretches

  • Thins when wet

  • Loses protection quickly

  • is no generally resistant to chlorine or sunscreen

Premium UPF fabric:

  • Holds its structure

  • Maintains protection

  • Is tested to UPF50+ standards (like ARPANSA in Australia)

  • is chlorine and pilling resistant

  • is quick drying

Why This Matters for Your Skin

Sun exposure contributes to:

  • Premature aging and fine lines and wrinkles

  • Sun spots

  • Skin damage and skin cancer 

UPF swimwear acts as a physical barrier — not something that washes off or needs reapplying.  Discover our luxury sun protection swim collection to find your perfect fit for those outdoor adventures.
