The Bucas Buzz-Off Zebra fly mask is the perfect complement to the Buzz Off Zebra fly rug or can of course be used on its own. Studies have shown that insects avoid the zebra stripes as opposed to plain colours, as the flies are confused by the contrast of the black and white stripes. The Buzz-Off Zebra fly mask therefore offers very good protection against flies and other insects for the eyes and the sensitive ear area.
