I too hold my Patagonia puff vest and pullover as my most prized hunting clothes (and general cold weather layers). Easy to pack, little weight, and warm even when damp. The fabric is slick and slips easily under other layers.
Liner socks work well and can be doubled up to resist blisters and add warmth. A second pair in the pack takes up very little space but can be really appreciated at times. I never need heavy socks.
Home Depot has $10 work gloves that are the ticket for dexterity and takes the chill off carrying a bow or rifle.
Rarely need or use long johns bottoms but silk weight capilene from Patagonia is light, slides under pants easily and can be stuffed in you pack if the day heats up. Use the tops in black as base layer in almost all situations. These can be a tick protector as well.
Add a fleece or silk neck gaiter and cabelas Perfekt boots and you got a very versatile combination. Works well with either Camo or Orange.
That's my two cents, Nick
