The Men's Patagonia Nano-Air Light Bottoms are mid-layer pants for cold-weather pursuits. As you move higher into the mountains, it's bound to get colder, but the light, 40g FullRange insulation provides the warmth and stretch necessary to push onward. The recycled polyester ripstop shell and lining are durable and smooth, allowing for abrasion resistance and easy layering. When worn on their own, a durable water repellent finish sheds light moisture to prevent light rain or snow from soaking through. Equipped with a zippered right-thigh pocket, a small essential or two can be kept safe without getting in the way of your harness.
