a few items I add to my usual gear here in Central/So Cal
(Utah/AZ mid-Sept archery deer seasons too) ;
1-sunglasses, the polarized kind with non-reflective lenses, matte finish frames. >Was on a ridgeline this past season, saw reflection flashes from below. It was 2 hunters looking up my way. one had reflective mirrored lenses. Kind of like a static sos signal.
2-uh, yeah, sunny CA....non-scented sun screen.
3-face paint for sure. too warm for face cover. that sun will reflect off your face like a light bulb. Couple stripes over the cheeks will do ya.
4-Turtle Skin brand snake gaiters. in outings over past years, Been struck 2x by rattlers on my stalks. Have avoided most of those camo Crotalinae! However, Buzz worms don't always buzz. Good thing for up to knee height snake protection.
5-2oz spray bottle of insect repellent, Permethrin type. not for skin use but retreat pant cuffs.
6-ziplock with a few non-scented wipes, reduce that sweat odor few times a day.
