Abstract
Methods of forming a stitched multi-layer fabric are provided. An embodiment method includes stitching an interior layer to a barrier layer, the interior layer comprising a first non-waterproof fabric and the barrier layer configured to inhibit fluid flow, disposing a face layer over the barrier layer without contacting the interior layer, the face layer comprising a second non-waterproof fabric, and melting a portion of the barrier layer to bond the face layer to the barrier layer and to fill stitch holes formed in the barrier layer during the stitching.
