A traditional stand-up pant for the young free-spirit in a durable, water-resistant nylon.
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.
UPF stands for “Ultraviolet Protection Factor.” This value represents the fractional amount of the sun’s harmful UV rays that pass through a fabric. A rating of “25” indicates that only 1/25th , or 4% of the UV rays pass through the garment.
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 USA test methods AATCC 183/ASTM D6603/ASTM D6544.
