Abstract
A waterproof, insulated multi-layer fabric structure is described, including a first and second layer to bound an interior volume. A baffle layer is located in the bounded volume and undulates between the first layer and second layer. The baffle layer is directly attached to the first layer. Adhesive tape portions are attached to the second layer to eliminate the need of stitching through the second layer, improving the structure's waterproof qualities. The baffle layer is attached to the adhesive tape portions which extend from the second layer. A method for manufacturing the multi-layer structure is also described.
