Teen temps or below (sitting) I'll wear my Montbell Alpine down vest over a mid-layer Patagonia R2 or R3 fleece jacket or a single Montbell Alpine down jacket (own both their down vest and jacket). Also have 2 Patagonia climashield vests for milder temps. All mentioned are light and highly packable.
I usually wear some combo of 2 baselayers, a light and med/heavy. Own various weights of baselayers: capilene, Smartwool, 32 Degrees (Costco), Orvis, and Pacific Trail etc. Quarter zips much preferred for the second baselayer.
For waterproof shells I have several hooded ones: highly packable E-Vent and a cheapo Frogg Toggs. And for closer hunts a Cabelas Whitetail Gore Tex shell and Columbia Big Game shell. Hoods are much preferred.
