"Might want to look into clothing marketed to hunters."
Good point, Nathan! The few 'outfitters' near me (still a day's travel) are fishing/hunting/outdoor work suppliers. Apparently those fellows do not care what something weighs, however (7 pound coat, anybody?). I do get some decent stuff from them all the same. Like socks.
I'm probably boring you now, but I'm told that a lot of 'camo' gear is a bit of a joke, because animal/bird eyesight is nothing like ours. Particularly, they see UV reflection. We might think we're totally stealth, but we actually look like big bipedal glowsticks to the animals. (If I saw a glowing blue creature in the woods, I'd take off too.) So (I'm told) unless you're buying special materials or special treatments, you're better off in black clothing than in most camo, because more UV is absorbed. That said, whatever I have that isn't black is green, grey or brown.
I'm pretty sure patience, quiet, slow movement and body language matter more, though (i.e., if you make eye contact, close your eyes right away and then blink often and slowly. Tells the animal you're indifferent to it, and not nervous or aggressive.) But if you can get out where most hikers and hunters don't go, you might well be the first human the animal has ever seen. It's amazing how some of them will get curious and approach when they've never seen the likes of you before. All you have to do then is not startle them.
