A protective garment made of material which includes a high barrier, multi-layer film incorporating EVOH laminated to a spun bonded polyester substrate. The film is a five layer construction with a layer of EVOH in the middle, bracketed by water resistant bonding resin layers and outer layers of polyethylene or polyester. The substrate is formed with low temperature binders and is calendered on both sides, the outer side being calendered much more extensively than the inner side. The material is joined together at pattern edges by thermal bonding under pressure or by a strip of the film thermal bonded to material segments.

A protective garment for hazardous chemical environments, comprising: (a) two or more adjacent segments of material having adjacent edges; (b) each of said material segments including a multi-layer film made of polymeric substance and having an intermediate EVOH layer, a polymer layer on each side of said EVOH layer, and a water resistant resin tie means between said polymer layers and said EVOH layer; (c) each of said material segments also including a substrate; (d) said film and said substrate being laminated together; (e) said garment further comprising a strip of said multi-layer film; (f) said adjacent segments being joined at said edges by placing said strip of film above said edges and bonding said strip of film to said adjacent segments to create a substantially moisture-impervious seam between said segments; (g) said garment being effective to protect a worker in a hazardous chemical environment while retaining its chemical resistance properties in the presence of moisture.
