so ive been doing alot of research on getting new basel layers for those cold cold ass all day sits. im leaning towards Minus 33 expedition weight merino wool .. i think its going to wick the best on the walk in and keep my warm in the sit. But i just came across DULUTH trading new Alaskan heavy weight baselayers .. mostly made with polartech .... also cabelas expedition weight baselayer system ... which i believe is also polartech ... just seeing what guys are wearing and thinking .. not afraid to put some cash on it .. cant put a price on comfort IMHO ..
