Abstract
An inexpensive breathable protective outer garment is produced from a breathable laminated fabric having a breathable film adhesively bonded to a nonwoven fabric. The film constitutes the outer layer of the garment and the nonwoven layer is on the inside. The seams of the garment are ultrasonically bonded such that the film sides of the laminate are in contact with each other during seaming.
