Our Sankaty Quarter-Zip, named after Nantucket's Sankaty Head, home to the Sankaty Head Lighthouse and the Sankaty Head Golf Club, is an endlessly versatile layer. Whether you dress it up with a button-down for a meeting or down with an On-The-Go Tee for an afternoon on the boat, the updated microgrid lining controls your temperature, and the fabric packs the perfect balance of weight and warmth.
