The Carlo full-zip sweater is made from merino wool. That means it has the uncanny ability to insulate when it's cold and expel sweat vapor when it's warm. That merino paired with silk and cashmere really ramps up the coziness. Throw in a fabulous intarsia (multi-color) knit pattern and you have a next-level sweater. The Carlo is available in both moss and charcoal camouflage.
