No maintenance, poor seam!

I bought the mask to be protected against the cold while skiing. When I got the mask, I have of course tried home first. The stop at the back of the head leaves to be desired very strong left, making the mask again slipping and not in place remains.

To actually get fixed reasonably mask I drew the Velcro strapping something, whereupon one of the Velcro surfaces has then already solved. : |

The processing of Nasenauslasses is not optimal, looks a bit like intended and failed. I definitely rate of the mask off!
