The coupler includes a first coupling portion including an interior passage through which the gas stream can pass in an axial direction between the first and second filter sections and a hook projecting from the first coupling portion. The coupler includes a gasket that sealingly engages both the first and second coupling portions when the first coupling portion is connected with the second coupling portion to form a substantially gas-tight seal.

Abstract: An item of footwear including an outsole secured to an upper is provided. A bootie is attached to the infill panel. The bootie and infill panel combine to form a cavity receiving the wearer's foot. The bootie is provided by a single air permeable, moisture vapor permeable, and waterproof sheet formed from a plurality of layers of material laminated together. The sheet forms at least one edge portion extending, at least one time, a distance between a toe end and a heel end of the bootie. A protection strip is attached to the outer surface of the sheet adjacent the at least one edge portion. A stitching seam is formed by a thread-type material securing the at least one edge portion of the bootie adjacent an outer peripheral edge portion of the infill panel. The thread-type material extends through the protection strip and the infill panel to form the seam.

Abstract: A bootie for use in a footwear item, a method of making the bootie, and a footwear item including the bootie are provided. The bootie provides the upper of the footwear item that will surround the wearer's foot. The bootie includes a body formed from a single air permeable, moisture vapor permeable, and waterproof sheet formed from a plurality of layers of material laminated together.
