Don't follow the guide's advice. Bring TWO headnets. They're cheap, light and critical.
And wear them both at the same time.
Wisdom here. While bear hunting, I wore one under my cap and one over it. The inside one had an area cut out to see through. The one over my cap kept the bugs away so they could not bite. The two on my neck and head kept them at bay there. Tuck in everywhere. I even wore two pairs of gloves. Last year in AK I got a few bites from some evil red colored mosquito like things. They raised welts that took weeks to go down. I always throw an extra or two in my duffel.
