Within hours of receiving the Patagonia Performance Twill Jeans, I was putting them to the test at a local climbing area. After a few knee bars and drop knees, I knew these were going to hold up well. I prefer the natural feel of cotton pants over some other synthetic options; they feel more durable and rugged, though oftentimes they compromise on flex. That is not the case with these pants—the fit is plenty comfortable to accommodate a hard day of adventure or a casual night on the town. Plus, many thoughtful features, like moisture-wicking and weather-resistant fabric, make these some of the most versatile pants on the market. Thanks to Patagonia’s commitment to sustainability, the materials can now be traced back to their origin, showing a dedication to organic inputs and fair-trade production. $99; patagonia.com.
