Abstract: Specific fabric articles exhibiting very low air and/or gas permeability (even upon application of high inflation pressures) and very high tear strengths are herein disclosed and claimed. Such a specific fabric also permits the incorporation of discrete openings (through cutting, for example) through which air and/or gas introduced by an airbag inflation canister will travel.
