I've been skiing and hunting and fishing so long that I have several layers to choose from. All must wick moisture and beyond that, I don't worry about brands too much. Most use the same fabric manufacturers like DuPont anyway. As for camo pattern, that is 100% marketing when it comes to deer. The old Woolrich black and red plaid still fools deer to this day, but buy what fits you and works best. I just layer up or down as needed.
That said, some of the best long johns I've ever owned were made by Patagonia, but I got them at cost and not at retail. I would never pay retail for brands like those. I have matching top and bottom Polar Fleece by Patagonia for my third under layer when it's very cold out. For my outer wear for deer in a stand, I have a bib overall set with a jacket in a jacket by Cabelas that has been terrific. Again, I can zip out one of the jackets if I don't need that extra warmth. The Cabelas are Real Tree, but any camo will fool a deer.
