Frequently Asked Questions

What is UPF50+ sun protection?

UPF50+ is the highest sun protection rating, blocking at least 98% of harmful UVA and UVB rays. Designed for the Australian outdoors, Toshi UPF 50+ Sunhats and Swimwear provide trusted protection for long days in the sun.

Toshi UPF50+ rating is achieved in the fabric manufacturing process. This ensures the safety and permanence of Toshi sun protection.

Alternatively, the UPF50+ rating can be achieved via a chemical treatment to the finished product. The chemical treatment is temporary with the potential for chemicals to be released from the fabric surface, creating a health and safety risk for precious babies.

When selecting sun protection, it is important to check how the UPF50+ rating is achieved.

Another important consideration for optimal sun protection is the shape of the sunhat. A sunhat with a wider brim will offer increased protection.

What are the benefits of Organic Cotton?

Toshi 100% organic cotton is soft, breathable and gentle on delicate baby skin. Grown without harmful chemicals, organic cotton offers a more sustainable and considered choice for everyday wear.

Our 100% cotton yarn is certified by the Global Organic Textile Standard (GOTS). GOTS is a third-party certification organisation, ensuring the organic integrity of the fibre from farm through to responsibly managed yarn production.
