This pullover is made with a moratronic diamond knit which is different than a classic quilting stitch-the benefit is that unlike quilted styles that might lose a thread over the years, this will keep it's pattern forever. We also used alcantara performance suede details on the placket which is machine washable and what they used for upholstery in high end sports cars-pretty cool, if you ask us. johnnie-O Rockwells Diamond-Quilted Henley Pullover in Blue
