The neck warmer is way too big! According to the description it should be for children, from the width wise he is (even size S / M), but so far that it fits more than a bull-necked prizefighter! To me he was too big, my little he was way too big. Since indeed fit 2 necks simultaneously purely! When I put it around my own neck, I can put your fingers in between and they spread by about 8 cm.
The material and the processing is, however, very very good, he feels - for the aforementioned prize fighter - very cuddly soft and pleasant to!
