A low permeability fabric and airbag formed therefrom suitable for use in protection of a vehicle occupant in the event of a collision are provided. In particular, the present invention provides an uncoated fabric preferably formed from a substantially symmetrical weave construction of nonsized nylon yarn at a fabric cover factor of not greater than 0.85. The fabric is characterized by an air permeability of not greater than 0.8 cubic feet of air per minute per square foot of fabric at a pressure drop of 125 Pa (0.5 inches of water) across the fabric. a method for formation of the fabric is also provided.
