Full zip sweaters provide instant on/off wearability at any given moment, ideal for our ever-changing weather climate. Superb quality, attention to detail and stylish clothing are the hallmarks of Calvin Klein. The soft-touch fabric which is a 50% Cotton/50% polyester blend is lightweight, breathable and moisture-wicking, all the attributes needed for comfort on those cooler days. Ribbed cuffs and hem provide that accomplished Calvin Klein look. The high-quality design with Insul-lite technology helps the sweater retain body heat for ultimate warmth on those slightly cooler days when a jacket would be too much.
