US Patent 9017505 Waterproof garment with invisible barrier seam

A waterproof invisible bather seam is formed between two fabric laminates, an outer shell fabric laminate and an inner lining fabric laminate. The seam includes an invisible seam tape that forms a hydrostatic bather within the seam. The design of the seam allows the formation of an effective hydrostatic barrier along the seams of a soft shell garment, while retaining flexibility, stretch, aesthetic appearance, and reversibility.
