Recommended by the Skin Cancer Foundation

Pairing function with fashion, we’re proud to share that the Skin Cancer Foundation recommends the material of every Carkella hat with a UPF 30+ or 50+ rating and a 3+ inch brim as an effective UV protectant.


The Skin Cancer Foundation is the only international organization devoted solely to education, prevention, early detection and prompt treatment of the world’s most common cancer. To earn the Seal of Recommendation, a manufacturer must provide scientific data showing that its product sufficiently and safely, “aids in the prevention of sun-induced damage to the skin.” The data is reviewed by a volunteer committee of photo-biologists — experts in the study of the interaction between UV radiation and the skin. Wallaroo’s sun protection hats have received this seal of approval. 

The criteria to earn The Skin Cancer Foundation Seal of Recommendation includes:

  • 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, a minimum brim width of 3 inches


What’s the difference between UPF and SPF?

SPF stands for Sun Protection Factor and is the rating for sunscreen, creams and cosmetics. It measures the amount of time it takes for sun-exposed skin to redden (after applying these products).

UPF stands for UV Protection Factor, and it measures the amount of UV radiation that penetrates the fabric of clothing or accessories. The tightness of the weave, the weight, type of fiber, color and amount of skin covered all impact the level of protection. 


Carkella UPF 30+ / 50+ Hats

Look for the UPF 30+ or 50+ icons when shopping for your Carkella hats. These fabrics are tested by the Australian Radiation Protection Agency and block 96-97.5% 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 Carkella hat only protects the skin it covers. Safeguard the rest of your body by wearing sunglasses and sunscreen.
