Abstract
An article including a woven fabric for impeding the passage of air, the fabric having an air permeability of less than about 15 cfm/ft.sup.2 and including at least one multifilament yarn having a longitudinal axis, the yarn being made of high strength filaments having a tenacity of at least about 7 g/d, a tensile modulus of at least about 150 g/d and an energy-to-break of at least about 8 J/g. Preferably, the high strength filaments are extended chain polyethylene.
