  • the present invention relates to breathable waterproof garments, and particularly but not exclusively to garments worn during outdoor recreation or outdoor sports.
  • a method of manufacturing a breathable waterproof garment comprising: forming a first garment layer in a stretched configuration over an oversized three-dimensional garment former having a profile extending substantially in three dimensions and corresponding to an oversized three-dimensional profile of the garment when worn; covering the first garment layer with an intermediate garment layer resistant to penetration by liquid water but permeable to water vapour; covering the intermediate garment layer with a second garment layer; and while the first and second garment layers are simultaneously stretched over the oversized three-dimensional garment former adhering the intermediate garment layer to both the first and second garment layers at a plurality of discrete securement locations (e.g. to form a discontinuous pattern of securement locations between each of the first and second garment layers and the intermediate garment layer to enable folding of the intermediate garment layer relative to the first and second garment layers).
  • a waterproof breathable (and windproof) garment having a profile extending substantially in three dimensions when in an unworn condition comprising inner and outer water-permeable stretchable garment layers and an intermediate garment layer that is waterproof (e.g. resistant to penetration by liquid water under normal conditions during wear) but breathable and allows significant stretching of the inner and outer garment layers (e.g. by at least 5% in at least one direction, for example by at least 10% in at least one direction, at least 20% in at least one direction or at least 30% in at least one direction).
  • the method of present invention provides a 1 -stage adhesive application process for the manufacture of waterproof breathable garments having a close-fitting profile extending substantially in three dimensions.
  • the garments made in accordance with the present invention may be formed with first and second garment layers having no or minimal seams (a crotch seam may be desirable for certain garments including leg parts) thereby maximising stretchability whilst avoiding or minimising the risk of water leakage through seams and potential for seams rubbing against a wearer's skin, or perforation of the waterproof intermediate garment layer.
