This is what I do.
I have a pair of Boure winter knickers.
Boure does custom, so you can have them as tights.
I had the insulating material go a few inches extra up my back, which is nice.
They also use soft and stretchy bib straps that don't dig in.
The link takes you to their winter tights. With boots, and tall socks, I prefer the knickers.

Over those I wear Sugoi Espresso pants.

I use a variety of base layers. The Corewarmer is my midlayer. Order TWO sizes larger
than normal, and ask them to make it TWo inches longer than normal. Trust me on this,
this is great bang for the buck in cold weather clothing.

The biggest problems are hands, ears and feet. You can use cheap ski gloves
if you ever did skiing. I need to cover my ears, there are a variety of choices, most not very good.
Feet can be a problem. But the solution depends on a lot of different things, you will have to try different stuff
and work it out.
