Hey Brian, the material on these pants is regular thickness. That said, you might want to consider insulated snowpants. I almost always ride insulated snowpants unless the weather is really mild (30+ degrees F).

I typed "insulated pants" into our search bar and got 20 men's snowpants, including the Poacher Insulated pant which is this exact pant with insulation. Put this URL in your browser to see the results:
