When you sleep in a sleeping bag, the part of the bag that's underneath your body is compressed, which significantly decreases it's level of insulation and increases heat loss through conduction with the cold ground. A sleeping pad isn't just nice padding for your back, it insulates you from the cold ground. The pad is worth more than it's weight.

Example:
Prior to Leave No Trace practices, one way of insulating yourself from the cold, hard ground was to pile up 6-12 inches of leaves, pine needles or pine boughs. This practice is of course outdated and will get in in trouble in many places. The modern approach is to use a foam or inflatable pad to limit heat loss through conduction and to make for a nice soft sleeping area.
Closed Cell Foam
Durable and it doesn't matter if you puncture it
Inflatable
Better insulation value to weight ratio
Generally more comfortable unless you puncture it

A Sleeping Pad is essential for insulating your body against the cold ground. This is NOT an optional item for winter camping.
Required (NOT optional) for snow outings
Vital if sleeping on snow or frozen ground
Ideally carry 2 sleeping pads if sleeping on snow or frozen ground
One closed cell foam - indestructible and multi use
Army closed cell foam is reasonably thick and affordable
One inflatable - better insulation/weight ratio
