Nice pad / sleeping bag system - Big Agnes Insulated Air Core Ultra Sleeping Pad

If you have to sleep on the ground this pad paired with the Big Agnes sleeping bag is a nice system. The pad slips into the slot on the bottom of the sleeping bag so you don't slide off the pad. The Air Core pad is easy to inflate to the level of support you like and deflate when you need to pack it up with the large valves. I haven't used it in colder tempatures yet so I cannot speak to the insulation value, but as far as sleeping pads go it works well.
