I bought 3x and they work wonders , I work in a chiller and my neck was always getting cold until I used one of the Warm du balaclavas. I fold the over the head part in and wear it around my neck and it works great . I also have to wear a hair net seeing I work in production and both work well together . No more cold neck and now I am all warm and toasty with this and my hoodie combined. Thanks for a great product 👍. Definitely recommend
