I just posted about Kuiu gear. My problem has always been trying to carry a complete tree stand setup, hike up mountains, hang and stand and sit in it all day without freezing.
The high end high tech stuff from Kuiu and Sitka show promise in making this kind of hunting more pleasant. If you get the right combination of pcs. I have yet to use it in bitter cold. But it is light and keeps the sweating to a minimum.
I've been using the merino wool socks too. Nice!
I use a Mystery Ranch Crew Cab backpack. My lone wolf stand goes in the pack. The pack is comfortable and can expand to haul almost anything you can think of . Having the stand against your back with gear tied to it limits what you can carry comfortably. An all day sit deep in the woods takes a lot of gear, clothing, food and water.
