To speed up the inflation of a second chamber of an airbag that is portioned into a first chamber including an inflator and the second chamber enclosing the first chamber and to facilitate the design of adjusting the shape and thickness of the inflated airbag, an airbag and airbag system are disclosed. In one form, the airbag includes therein first and second inner panels to partition the interior of the airbag into a first chamber and a second chamber that encloses the first chamber. The second inner panel has communication holes for communicating the first chamber and the second chamber with each other. The outer peripheries of the inner panels are joined together with a seam. A jet of gas emitted from gas ports of the inflator is supplied directly into the second chamber through the communication holes.
