Just brought our horses in from the field for the night and continue to be so pleased with their new Catch Masks which are a very sturdy fly mask that has an opening at the bottom for attaching a lead line. No need for a halter and a fly mask; this is an all in one product. This is the first fly mask that I can truly say will be used from one fly season to the next. The Catch Mask is really a unique product; none other like it on the market. Not only that, it comes in colors to match your horses own color so as not to attract the attention of pasture buddies who might like to pick at the mask as many horses will do.
