The Cozy Fleece Vest are made from a soft, warm fleece fabric to keep your animal warm during chilly winter days or nights. Designed with a strong zip up the backline will keep your animals belly covered for extra warmth and makes it virtually impossible for animal to take off. The fabric is breathable and lightweight which is great for washing as will dry in a day so can be clean and then worn again that night. (great for those smelly bucks/rams)
