Coolibar UPF 50+ Quality Guarantee

You can depend on the Coolibar UPF 50+ quality guarantee for superior sun protection items.

At Coolibar, we carefully develop technical fabrics that are then thoroughly tested at independent labs to ensure each product meets or exceeds our UPF 50+ standard. This UPF 50+ rating is the highest rating available to clothing and blocks more than 98% of harmful UVA and UVB rays. We also place a hang tag with the percentage UV blocked and the UPF rating on every garment we manufacture.

Because we are so meticulous about testing, we can absolutely guarantee UPF 50+ protection from the first day our product is worn until the last day. Our UV testing of fabrics significantly exceeds all published American standards.

  • 1. UV transmittance tests are performed according to the American Association of Textile Chemists and Colorists Test Method 183 (AATCC 183)
  • 2. Fabrics are tested both before and after life cycle exposure to laundering, sunlight, and chlorinated water according to American Society for Testing and Materials D 6544 (ASTM D 6544)
  • 3. Garments are then labeled according to the guidelines specified in American Society of Testing and Materials D 6603 (ASTM D 6603).
  • 4. Coolibar performs this testing for multiple samples from every dye lot of every fabric used in production of all Coolibar sun protection clothing items.
