Wear it as a baselayer on frigid ski days or as a light sweater for cool-weather hikes or chilly summer summits. This midweight turtleneck is 65 percent merino and 35 percent Cocona polyester, a blend that results in a soft, supple, itch-free fabric that has the durability, temperature regulation, and anti-stink properties of wool. “This shirt morphs into whatever I need it to be,” says our Rocky Mountain editor, who has worn it steadily for 10 months.
“I stayed at an eerily perfect temperature whether hammering uphill, stopping for a ridgetop lunch, or coasting through sun and shade in deep, windy canyons,” he says. The long-tailed, relaxed cut is shaped and stretchy enough for good skin contact to maintain wicking during heavy exercise, and the double-layer turtleneck stands up and protects necks without strangling. $150; 10.4 oz.
