What I like good, is that the material is really comfortable on the skin. Even from the top and bottom most of the neck is well warmed with me.
About the fact that on the inside runs a large seam, I can ignore for such a low price. Schön would have been to have no seam, but for a higher model I was a cheapskate. I just wanted to have mentioned, since it is not apparent on the date figures available.
Not so good, however, I find that there is no setting. I imagined the material slightly elastic - ie so that it is a bit tighter around the neck after it has pulled over the head. Instead, it is quite loose, and it gets a good amount of cold air to the neck, if one does not include the jacket up above. Models from other manufacturers build a tapes, using which you can create the part a little closer to the neck.
Bottom line, I find the Halswärmer quite well. He does not tear me away and is anything but a high-end model, but for such a small market, it would also be covered to expect more.
