I have tried different combinations without breaking the bank, bought some under armour cold gear base layer a few years with high hopes and wasn't impressed. Having sons in the military, my oldest gave me some light weight army silks and the waffle mid weights. Wear the silks than the waffle mid weights. Hands down the best base layer i have found, the wicking action keeps me from getting cold after I worked up a sweat, i have always been a fan of the outerwear with midweight coat zippered to a outer shell like the Cabela's silent stalker parka. Not sitka gear but it keeps me warm and dry hunting in the snow belt of northern Ohio.
