I thought the idea was great: a fly mask made of elastic material which tightly enough so that no flies sitting among them come and eliminates chafing so my Haflinger can wear in an open stable 24 and so has its quiet before bloody ears by blackflies. He has a large head, so I have the mask ordered in size Warmblood and the fit was also really good, unfortunately, after only one day in the paddock broken although he does not chafe or has tried to get rid of the mask, and thus they missed their purpose perfectly , Schön would be a tighter mesh material that is sewn so that it keeps distance from the eyes, then the whole mask would also durable. I can see the mask luckily send back.
