Abstract
Abstract The present invention features a removable liner for headgear. The inventive liner is specifically configured for placement within a cap member, hat, or any sort of headwear for enhanced thermal comfort. The liner is comprised of two shell layers that are made from choice performance materials. The two constituent shells are formed together to provide localized climate control for the head of the wearer. A first inner shell, adapted for contact with the wearer, is an ultrathin, thermally reflective, synthetic, microfibrous fabric. This inner shell removes moisture and allows airflow (for heat and perspiration removal. The second, outer shell is a multi-membrane fabric, forms an insulative, breathable, windproof, waterproof layer that lies between the headgear and the first inner shell.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
197 words
An insulative headgear assembly comprising: a headgear member having a dome-shaped, substantially hemispherical portion configured and arranged to be worn on the head of a wearer, said headgear member having an interior and an exterior, an upper, distal portion and a lower, proximal edge portion, said interior being oriented to face the head of a wearer, said exterior being oriented for contact with the atmosphere surrounding a wearer, said head gear member having fastening means located on said interior for removably attaching to said headgear a removable insulative lining; and a removable insulative lining for selective placement within the interior of said headgear member, said lining having a dome-shaped hemispherical portion configured and arranged to be worn on the head of a wearer, said lining having an interior, an exterior, an upper, distal portion, and a lower, proximal edge portion, said lining comprising a composite structure having a first outer shell which directly contacts said headgear member when positioned therein, said first, outer shell comprising a multi-membrane fabric, and a second, inner shell adapted for direct contact with the head of a wearer, said second, inner shell comprising an ultrathin, microfibrous, synthetic, thermally reflectant fabric material layer.
Claim 2
Dependent Claim
197 words
An insulative headgear assembly comprising: a headgear member having a dome-shaped, substantially hemispherical portion configured and arranged to be worn on the head of a wearer, said headgear member having an interior and an exterior, an upper, distal portion and a lower, proximal edge portion, said interior being oriented to face the head of a wearer, said exterior being oriented for contact with the atmosphere surrounding a wearer, said head gear member having fastening means located on said interior for removably attaching to said headgear a removable insulative lining; and a removable insulative lining for selective placement within the interior of said headgear member, said lining having a dome-shaped hemispherical portion configured and arranged to be worn on the head of a wearer, said lining having an interior, an exterior, an upper, distal portion, and a lower, proximal edge portion, said lining comprising a composite structure having a first outer shell which directly contacts said headgear member when positioned therein, said first, outer shell comprising a multi-membrane fabric, and a second, inner shell adapted for direct contact with the head of a wearer, said second, inner shell comprising an ultrathin, microfibrous, synthetic, thermally reflectant fabric material layer.
Claim 3
Dependent Claim
24 words
