During warm summer months horses can be bothered by flies, nats, horseflies and other pesky insects. We have several fly sheets to protect your horse against them, such as this fly sheet with neck and hood. This rug has a detachable neck and hood, which can be taken off when flies and other insects are less active. The rug has a belly flap which fits nicely around the belly and is attached twice with a Hook-and-loop fastener and surcingles which prevents it from shifting.
