Chew and spit or chew and swallow. I tried a neck gator once and for cycling, it's hot as heck to wear when generating so much heat that needs to be carried away. Those bugs, though annoying will be gone soon anyway. But they are protein too!
You'll find that masks like we wore for COVID are hard to breath through when they get wet with sweat.
The netting, I don't know. How will you keep it from being blown against your sweaty face?
