Simple and soft as cotton, this is the perfect sweater for layering over a dress shirt, polo or tee. And while it s made the old-school way—fully fashioned piece by piece to layer bulk-free over polos and tees—it provides state-of-the-art performance and longevity. Innovative cotton modal yarns ensure our smoothest sweater fabric that resists pilling, retains shape and stays bright even after many a trip through the wash. .
