I have First Lite, Ist Gen Kuiu, Patagonia, Mountain Hardwear, Icebreaker, Smartwool, Arc'Teryx and Core 4 Element Merino wool (i am always wearing at least one piece of merino every day).
If camo is a priority, then First Lite or the Core 4. If drab muted tones work for you, then Arc'Teryx and Icebreaker. Don't rule out the merino/poly blends. If they are 65/35, you get the benefits of no funk from merino and better wear/easier clean of poly (Patagonia and Mountain Hardwear). Don't go less than 60/40.
