The surprisingly soft SmartWool Zip-Mock Turtleneck ($74) is made from a blend of Merino wool and secret “smart technology.” The company asserts the combination wicks 27 percent more moisture away from your body than any other synthetic fiber of similar construction. And SmartWool actually works with your body heat to evaporate that moisture once it’s wicked away, which helps eliminate odor. The company is so sure of its product it will give you your money back if you’re not completely satisfied. Contact SmartWool at (970) 879-2913;
