Head Nets work very well in combination with insect repellents to double your defences and they can also be used quite effectively on their own in low risk areas, thereby allowing you to use less insect repellent - not always a pleasant thing to be smearing around your face!
Available both untreated or treated with Permethrin insecticide and with hole sizes ranging from quite large for mosquito protection in hot and humid climates to very small for protection from midges in cooler climates.
