UPF Fabric (15 to 50+)

Products with the UPF designation provide built-in sun protection that won’t wear off.

To achieve sun protection, we take a varied approach depending on the degree desired and the fabric used. Elements of the strategy can range from yarn selection to fabric construction to the use of special finishes (especially for light colours).

How products are rated

Patagonia products with rated UPF protection are tested independently to meet Australian/New Zealand or AATCC protocols.

Our rating system works as follows:

• 15 – 24: a rating of Good*
• 25 – 39: a rating of Very Good *
• 40 – 50+: a rating of Excellent*

*When tested in accordance with Australian/New Zealand test methods AS/NZS 4399 or AATCC 183/ASTM6603/ASTM D6544.
