My mare has been carrying the mask for several weeks for her blue eye and light nostrils. He gives her good visibility and seems resistant. I took a cob size for my Horse Paint; I am mixed on the waist. It is perfect in terms of ears, the maintenance is well at the level of the ganaches by tightening the scratchs thoroughly but the descending part on the nose is a little long so it drags on the ground and is damaged quickly. In addition, it irritates the skin a little on the tip of the nose. The positive point is that this part can be withdrawn but the clear nostrils welcome sunburns. After finding the mask on the ground in pasture, I added a wide halter above. Despite some negative points, I am rather satisfied with the product.
