Patent drawing
Patent drawing from the official filing.

Nike describes a knit fabric made of two layers connected by small threads to create air gaps for cooling. The design adds a folded trim piece along the edges, like cuffs or waistbands, to strengthen areas that usually wear out quickly.

Why it mattersThis could make athletic clothes last longer without sacrificing the airflow that keeps runners cool.

The textile includes a first knit layer, a second knit layer, and tie yarns interconnecting the layers. The textile may incorporate a trim piece along an edge to reinforce high-stress areas such as sleeve cuffs, waistbands, and neck openings. In some implementations, multiple knit spacer textiles are joined at a seam using one or more trim pieces, which may be bonded via welding, adhesive application, or stitching.
