The Skin Cancer Foundation recommends the material of every Wallaroo and Carkella hat with a UPF rating

  • A 3+ inch brim is an effective UV protectant.

Skin Cancer Foundation Seal of Recommendation requirements:

  • An ultraviolet protection factor (UPF) of 30 or higher
  • Acceptable test results according to the American Association of Textile Chemists and Colorists method or AS/NZS Standard
  • For hats, in addition to the fabric requirements specified above, a minimum brim width of 3 inches

UPF Fabric Protection

Look for our sun icon on our sun protection hats to determine which ones have a UPF rating of 30+ or 50+. These fabrics are tested by the Australian Radiation Protection Agency and block 96 to 97.5% of the sun’s ultraviolet rays. Ultraviolet radiation, or UV, is present in sunlight. The Ultraviolet Protection Factor (UPF) shows how well a fabric protects your skin from solar UV. Always remember that a Skin Cancer Foundation approved hat only protects the skin it covers. Safeguard the rest of your body by wearing sunglasses and sunscreen.

What’s the difference between SPF and UPF?

SPF stands for Sun Protection Factor and is the rating for sunscreens and other sun-protective products. It measures the amount of time it takes for sun-exposed skin to redden. SPF is for creams and cosmetics.

UPF measures the amount of UV radiation that penetrates a fabric and reaches the skin. The tightness of the weave, the weight, type of fiber, color and amount of skin covered all affect the amount of protection provided. UPF is for clothes and fabrics.
