## Abstract

A headgear assembly including a flexible cap and an insulator adapted to increase the heat retention of the cap. The cap includes an interior surface and a peripheral edge which surround and define a hemispherical interior cavity. A sweatband is affixed to the peripheral edge of the cap and is located adjacent the interior surface of the cap. The insulator is disposed within the interior cavity of the cap and includes a peripheral edge disposed between the band and the interior surface of the cap which retains the insulator within the cap.

## Claims

### Claim 1

A headgear assembly comprising:
a head covering having an interior surface, a peripheral edge, and an interior cavity defined by said interior surface and said peripheral edge;
a band affixed to said interior surface of said head covering adjacent said peripheral edge; and
an insulator removably received within said interior cavity of said head covering and having a peripheral edge disposed between said band and said interior surface of said head covering;
said insulator comprising at least one panel forming a generally dome-shaped structure and said panel including at least one layer of insulation and at least one layer of covering fabric secured to said layer of insulation; and
said layer of covering fabric being water-resistant.

### Claim 2 (depends on 1)

The headgear assembly of claim 1 wherein said layer of covering fabric is air permeable.

### Claim 3 (depends on 1)

The headgear assembly of claim 1 wherein said layer of covering fabric is substantially waterproof.

### Claim 4 (depends on 1)

The headgear assembly of claim 1 wherein said insulator comprises six panels and each said panel includes at least one layer of insulation and at least one layer of covering fabric.

### Claim 5 (depends on 1)

The headgear assembly of claim 1 wherein said at least one panel includes one layer of insulation sandwiched between two layers of covering fabric.

### Claim 6

A headgear assembly comprising:
a flexible cap having an interior surface, a peripheral edge, and an interior cavity defined by said interior surface and said peripheral edge;
a band affixed to said interior surface of said flexible cap adjacent said peripheral edge; and
a dome-shaped flexible insulator removably received within said interior cavity of said flexible cap and having a peripheral edge disposed between said band and said interior surface of said flexible cap.

### Claim 7 (depends on 6)

The headgear assembly of claim 6 wherein said band is made from an absorbent material.

### Claim 8

A headgear assembly comprising:
a cap having an interior surface, a peripheral edge, and an interior cavity defined by said interior surface and said peripheral edge;
a band affixed to said interior surface of said cap adjacent said peripheral edge; and
an insulator removably received within said interior cavity of said cap and having a peripheral edge disposed between said band and said interior surface of said cap;
said cap including a back portion with a semicircular cut-out region;
said cap including adjustment means attached to opposing sides of said cut-out region for adjusting the size of said cap; and
said insulator including a semicircular cut-out region generally aligned with said semicircular cut-out region in said cap.

### Claim 9

A headgear assembly comprising:
a head covering having an interior surface, a peripheral edge, and an interior cavity defined by said interior surface and said peripheral edge;
a band affixed to said interior surface of said head covering adjacent said peripheral edge; and
an insulator removably received within said interior cavity of said head covering and having a peripheral edge disposed between said band and said interior surface of said head covering,
wherein said insulator includes a second band joined to said peripheral edge thereof.
