I use WoolPower from Sweden and get them from CanadianOutdoorEquipment. It's pricey, but a pair should last for years if you treat it right. The 200g works great for most conditions. I save the 400g for very cold days and sometimes for ice fishing. Skip the jeans. Cotton is cold. Wear the merino against your skin except for underwear under your bottoms to keep the bottoms clean. Carry your jacket and hat in so that you don't get too hot. You can put your jacket on when you get to where you're hunting.
It sounds odd, but avoid washing the merino except maybe at the end of a season, if then. Every time that you do so it gets a bit thinner and thinner means less warmth. That's just the nature of a washer and dryer. I avoid both as much as possible for my merino wool. Instead, hang it up to air it out. You won't stink and it's comfortable.
I've tried all the fancy, synthetic material name brands and for me, and this merino wool just works. I'm usually in the woods for weeks deer hunting and need to be quiet, warm, and try not to retain too much scent in my clothes. The synthetic name-brand stuff seems to retain some noticeable scent even after running it through the washing machine. I'm not a fan. There are probably others that work just as well as the WoolPower stuff, but I stopped looking when I started using it since it works for me.
Good luck! I hope that you found something this year and were successful hunting!
