Removable, reusable, washable liner for use with various types of head gear

Abstract: A lining for use under head gear—such as baseball hats, top hats, helmets, cowboy hats, hard hats, beanies, stocking caps, etc.—comprised of two layers, one specifically for comfort, in both softness and breathability, and a second specifically for the filtering of salt, dirt, oils, particulate matter and other undesirable constituents contained in the sweat of the wearer. The two layers are each comprised of four roughly equal pieces of an isosceles triangular shape that are stitched together to form a half-dome. The two layers are then stitched together along the bottom circumference of said dome two form a single half-dome comprised of two individual layers. The two layers employ their relative absorbency to transport moisture from the head of the wearer and into the lining. The outer layer employs its maximal surface area to filter and store the sweat of the wearer, while maintaining breathability. Together the two layers form a lining that both protects the head gear from stains, discoloration, premature wear and odors, maximizing the effective lifespan of the head gear, while also maximizing for the wearer comfort both in terms of fit and breathability, maximizing the effective value of the head gear for the wearer.
