The resultant inflatable fabric composite thus includes inflatable areas separated, at least partially, by seamed barrier areas.

These shear seams thus provide a relatively effective manner of reducing air permeability within the entire fabric article. Such a fabric may be utilized in numerous and various applications wherein fabric inflation is desired or necessary.
