The best insulated ski pants for extreme cold pair at least 60-100g of synthetic insulation with a waterproof rating of 10,000mm or higher and fully taped seams — Helly Hansen Legendary Insulated and The North Face Freedom Insulated are two real-world proven options in that range.
I live in the Midwest now, which means plenty of bone-cold, wind-whipped days at the hill instead of Colorado powder days — and that's exactly when a shell pant with just a base layer underneath stops cutting it. If you're standing in the lift line doing the cold-leg shuffle, you don't need another layer, you need pants built with real insulation in the first place.

For sustained sub-20°F temperatures or a lot of standing around (ski school, lift-serving, watching kids), look for 80-100g of synthetic insulation; for cold but active days where you're skiing most of the time, 60g is usually enough and keeps you from overheating.
Generally yes — insulated pants are built for genuinely cold days, and most riders find them too warm once temperatures climb into the 30s and 40s, which is when a shell pant with a removable base layer makes more sense.
Look for at least 10,000mm, which handles wet snow and sitting on chairlifts fine for most resort skiers; if you're regularly in deep, wet snow or doing any backcountry travel, 15,000-20,000mm with fully taped seams is a safer bet.
Yes, a lightweight base layer under insulated pants is normal and recommended for genuinely cold days, but you generally don't need a heavyweight base layer underneath since that combination can trap too much heat and leave you sweaty.
Shell pants have no built-in insulation and rely entirely on the layers you wear underneath, while insulated pants have a synthetic fill sewn into the shell itself — insulated pants are warmer out of the box but less versatile across a range of temperatures than a shell paired with swappable base layers.
