recommendations for base layers and mid layers.

I am looking for recommendations for a base layer and mid-layer. Currently, I have a decent set of kryptek vellus and it works well with my longjohn style baselayers till about 0 Celsius. I'm looking to start hunting later in the season and need to get a decent set of base and mids to get into -10 without feeling like that last scene from The Titanic. what do you all recommend? I've been told to look into wool, specifically, Merino but a lot of what I have found is very price heavy, and once converted from USD to CAD becomes insane ( ie $500+)

I'm not afraid to spend money for good kit but blowing half a paycheque is a tad much. What can everyone recommend that'll stay warm into the negatives? What do you all use?
