The invention relates to a method to connect a baffle and an internal structure to the outer-shell of a sleeping bag, an insulated jacket and a tent. A waterproof, insulated multi-layer fabric structure (10) is described, including a first layer (12) and a second layer (14) to bound an interior volume (16). A baffle layer (18) is located in the bounded volume (16) and undulates (20) between the first layer (12) and the second layer (14). The baffle layer is directly attached to the first layer (12). Adhesive tape portions (24) are attached to the second layer (14) to eliminate the need of stitching through the second layer (14), improving the structure's (10) waterproof qualities. The baffle layer (18) is attached to the adhesive tape portions (24) which extend from the second layer (14). A method for manufacturing the multi-layer structure (10) is also described.
