Want to stay warm in the field? You know it starts with the right base layer: our Women's Pecora Lightweight Merino Crew. We make it using an exclusive, new DuraSpun Merino fabric—Merino fibers wrapped around a single strand of Cordura® thread for incredible strength. In other words, the Women's Pecora Lightweight Crew is more than soft, comfortable, moisture-wicking and naturally odor-resistant, it's unbelievably tough, too. Just like you.
