I never know whether an item's fit will mean that I need a medium or a large. The medium size in this sweater works for my 5'11", 170 pound frame. The colors are great, and I hope that it lasts a long time.
Very soft and lightweight, and my son (for whom it was a gift) likes it very much. Very nice looking, too. Hopefully, it will wear as well as it looks and feels.
Everyone who received this vest as a gift, LOVES it. It is soft and flexible, not at all stiff or too heavy, yet it is warm. You are pretty much guaranteed to make a hit giving this.
