The set of four Rambo boots helps protect the horse's limbs from the annoyance of insects during the warmer seasons, ideal for the paddock. The fabric is made with the Vamoose Anti-Fly treatment, which helps keep flies and insects away from the sensitive lower part of the horse's legs. The Rambo Fly Boots are also breathable thanks to the innovative polyester Airmesh which promotes maximum air circulation by dispersing heat rather than retaining it.
