Yeah, I don't know why I haven't had problems with blaze orange. It's obviously not the first thing I grab, but I do hunt on private land where the deer aren't being harassed and pushed around, so maybe that's why?
That's a good point to bring up about buying second hand! And, just to be clear, I'm totally not against spending money if you have it available to spend. Heaven knows I've put in my fair share of my paycheck into bowhunting! If you're comfy in Sitka cold gear, that's great! I just think this is more about "bucking the trend" of the TV hunting shows in their completely decked-out head-to-toe X brand camo (that they probably got for free because of a sponsorship) and hearing those same people say "you need this gear to bowhunt" (and, worse, reading keyboard warriors typing the same thing). Even if you were a head-to-toe Sitka guy, you do you!
All I have is my own personal experience where I've bagged deer wearing wool plaid (from a tree, ground blind, and makeshift cover) and I've heard stories from a good bowhunter friend who wears Sitka about getting busted. Obviously, he's been successful and I've been busted before, but I really can't say how much of it is based on our outerwear choice vs things that I know do make a difference (making a sound, moving, the wind swirling, etc.).
