Abstract: In one aspect, a multilayer jacket wearable by a child comprises an outer jacket layer made from a first, compressible material and an inner jacket layer made from a second material that is either non-compressible or significantly less compressible than the first material. The jacket includes a pair of layer interconnection fasteners configured to fasten together anterior panels of the respective jacket layers. Each fastener is situated on a respective side of a vertical jacket midline along a line from a first respective point at or near a bottom edge of the jacket to a respective shoulder of the jacket. The fasteners are sufficiently spaced to accommodate between them a fastened child safety seat harness when the outer jacket layer is open and portions of the anterior panel of the outer jacket layer are folded open at the respective fasteners.

Abstract: A pre-filter kit and related method of use with an air filter associated with an intake of a machine is provided. The kit can include a sheet of pre-filter material, an adhesive component, such as an adhesive on a release liner, and one or more optional bands. The method can include: measuring a height of the air filter, cutting the sheet of pre-filter material so that the sheet includes a top edge and a bottom edge separated from one another by the height, as well as a first end and an opposing, second end; applying adhesive to the first end; and wrapping the sheet around the air filter so that the first end overlaps the second end to secure the first end to the overlapped portion of the sheet. The pre-filter is secured to the air filter so as to impair dirt, dust and debris from entering the air filter.
