We put a cozy spin on a classic look with this snuggly sweater—think super soft baby alpaca wool from Peru and extra-fine merino wool, all in a warm waffle stitch. You'll find this sweater does an A+ job at thermoregulating, keeping you at just the right temp for comfort. A ribbed knit at the cuffs and hem finishes the look.
