Like most of you I hate wearing anything, but feel you needed to, so I use the spando-flage, a strechy-elastic-netted head cover. Only thing is I cut the top off then wear it upside down. Most of the time it is lowered around my neck and when like a neck gaiter. Sucks when it is hot though. Anytime I foresee action or am in the shadows I pull up over the nose and below the eyes, kinda bandit style with a bandanna.
Burnt cork is my second choice, always have one in a fannie in pack.
Should probably add that I always grew a beard each hunting season, starting in July until it the brown hair stated turning gray.
