My husband loved his vest! It is a quality, normal weight material. I was a bit worried before purchasing because we bought a heating vest from a different brand a few years ago and it felt and looked weird, like a space blanket or something similar to that. This vest could be mistaken for a Columbia or a RL Chaps vest. It warms nicely and I would say fit is on the small size. We sized up one size and it fits beautifully. Great purchase, especially on sale!!
