A method for creating rainwear that is waterproof yet allows the body's heat and moisture to vent is disclosed, including a shell and a liner, wherein the shell material is waterproof, and the liner material is waterproof and may or may not be breathable and vents placed at intervals in the fabric of the liner that allow for free air flow between the interior and exterior of the garment to achieve breathability by virtue of the vents. The garment may be made of materials that are inherently flame resistant for use where there is a danger of flash fire, such as high-voltage electrical work and petroleum production. In some embodiments, vents are inserted within apertures defined by a garment and include a base with inner and outer ridges surrounding a central opening and a cover having a perimeter extending between the inner and outer ridges.
