Kalf Kozies Calf Ear Muffs are a ranch essential for cattle producers facing cold weather. Newborn calves are particularly vulnerable to frostbite and cold stress — which can slow growth and reduce market value. Crafted from quality polar fleece, Kalf Kozies retain warmth, wick moisture, and protect delicate ears from the elements while allowing calves to nurse and move comfortably. The stretchable, one-size-fits-most design fits securely without restricting movement, and a faux leather ear tag patch lets you keep track of individual animals with ease. Machine washable and reusable, this calf warmer is a practical investment for any herd exposed to chilly conditions during calving season.
