The 2 in 1 Spray & Shine Protect is made with vegan silk and effectively protects your horse from stinging or biting insects (mosquitoes, flies, ticks, midges, horseflies, grass mites) for up to 24 hours. At the same time, the spray makes the fur and mane appear super shiny. Despite the silicone-free ingredients, it makes the mane easier to comb.
