Lacking fur, feathers or scales, we humans have to think up clever ways to protect ourselves from the sun. 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 colors). Patagonia products with rated UPF protection are tested independently to meet Australia/New Zealand or AATCC protocols. A rating of 15-24 earns a product a rating of “good”; a rating of 25-39 is "very good"; and a rating of 40-50+ is “excellent.” * * When tested in accordance with Australian/New Zealand test methods AS/NZS 4399 or AATCC 183/ASTM6603/ASTM D6544.
