I bought this several years ago for my 7-year-old foster son, who loved it because he said it was the only sweater he ever had that didn't itch.  That's because its made of alpaca, which has a natural softness to it. He called it his "animal sweater." 

I don't have a child sized mannequin, so it appears in the photographs rather broad in the chest, but is a perfect fit for a young boy.
