The UV-resistant, well-ventilated fine mesh protects your horse's legs from the knee down to the coronet band from excessive sun exposure and allows for even airflow around the lower legs during the summer heat. Reduce stressful and continuous stomping, leading to joint pain, hoof damage, and muscle fatigue. Soft, comfortable elastic with fleece at the top and bottom keeps the boot in place while preventing dirt, flying particles, or pollen from entering the boots and causing discomfort around the horse's legs. Built-in Nylon Maintains Shape: A sturdy built-in nylon reinforcement in each boot keeps the leg wrap upright and prevents it from sliding down when worn for extended periods. Full-length heavy-duty Velcro closures down the shin ensure a secure fit over the leg and eliminate the risk of slippage, even during exercise. Easy Maintenance: Toss into the wash or gently spray with water, quick-drying for repeated use in the stable or pasture. One size fits all. 2 color options: Purple and Black.
