Baffle constructs for insulative fill materials

This invention describes a way to make insulated fabric, like for jackets or sleeping bags, using a single piece of woven material. Instead of sewing separate fabric pieces together to form pockets for insulation, this method weaves multiple layers simultaneously, creating integrated pockets (baffles) that can expand to hold insulating fill. The claims specifically focus on this being a single, seamlessly woven fabric where the layers are joined to form these expandable baffles, which can lie flat when empty.

Why it matters: The core challenge in 2016 was likely the complexity and cost of manufacturing a "unitary, seamlessly woven" multi-layer fabric with offset baffles. Over the past decade, advancements in automated textile manufacturing and 3D weaving technologies have likely made such intricate, multi-layered fabric structures more precise and cost-effective to produce.
