Question: what is the difference between 2 ply and 4 ply cashmere?
Answer: How Many Plies of Cashmere Yarn Should My Sweater Have? ... A 2-ply sweater is the most common on the European market, and you can wear it all-year-round. 4-ply sweaters are perfect for the cold days in spring and fall, when it's not too windy - you can wear them without a jacket or a coat, as they keep you perfectly warm.
