Almost ridiculously thick. But they are the warmest
These pants are so thick one can hardly move in them. And they need a waist adjustment possibility.
Otherwise, they are the warmest out there and the suspenders are really wide, well designed and comfortable.
Another inch in the inseam would be welcome. But for the absolute extremes of cold, these are it. And they even have a pocket. Just be careful trying to run in them. (-:
