    Great quality, color, look and price! So happy the yellow was back in stock when I purchased
    Oh my gosh. I absolutely love this sweater on my 44-year-old son. He loves it as well. He is wearing a size medium in the picture. Great quality, launders as well. He simply washes it in the machine with cold water and then puts it on a hanger to dry. It is one of his faves!
