I used to have a fleece sweater which kept me warm, but which does not "breathe", i.e. you can get really sweaty. This wool sweater keeps me warm without getting sweaty.
My husband justs loves this sweater, he has owned it for some time now. I washed it without thinking the other day and put it in the dryer....it shrunk...now I own it! Read the label before laundring it!!!! I will be ordering him a new one.
