A hot air balloon is hollow (naturally) and is filled with the hot air that gives the balloon lift. By surfing the web a bit, one can probably find a picture that gives at least a partial view of the inside.

The balloon will shrink when it goes outside. How much it shrinks will depend on the temperature difference. As temperature decreases the gas(ses) in the balloon decrease in volume causing the balloon to shrink.
