Udder Tech Waterproof Milking Sleeve Duo with Thumb Hole features an innovative design when it comes to milking sleeves. Covers your shoulders and won’t slide down, because the helpful elastic strap located behind the neck connects the shoulders and keeps the sleeves in place. The thumb hole anchors the sleeves in your gloves and prevents water, dip and debris from touching your skin. Designed to keep chemicals and manure from arms and clothing while milking.
