## Abstract

Protective garment for environments having high radiant heat loads and/or high conductive heat loads is described. A protective footwear article and method of making includes an upper with an opaque outer layer; an inner layer; and a thermally reflective layer positioned between the outer layer and the inner layer, the thermally reflective layer having a reflective surface facing the outer layer.

## Claims

### Claim 1

A protective footwear article including an upper, the upper comprising:
an opaque outer layer;
an insulative inner layer; and
a thermally reflective layer positioned between the outer layer and the inner layer, the thermally reflective layer comprising an infrared reflective material laminated to a fabric substrate, the infrared reflective material facing the outer layer and the fabric substrate facing the insulative inner layer, wherein the infrared reflective layer comprises an aluminized surface that is flexible and conforms to movements of the footwear upper without cracking or restricting movement of the footwear.

### Claim 2 (depends on 1)

The protective footwear article of claim 1 wherein the fabric substrate comprises a knit substrate.

### Claim 3 (depends on 2)

The protective footwear article of claim 2 wherein the knit substrate comprises polybenzimidazole and poly-paraphenylene terephthalamide.

### Claim 4 (depends on 3)

The protective footwear article of claim 3 wherein the knit substrate weighs about 5 ounces per square yard.

### Claim 5 (depends on 1)

The protective footwear article of claim 1 wherein the thermally reflective layer weighs about 7 ounces per square yard.

### Claim 6 (depends on 1)

The protective footwear article of claim 1 wherein the thermally reflective layer defines at least one vent.

### Claim 7 (depends on 1)

The protective footwear article of claim 1 wherein the protective footwear article is a boot.

### Claim 8 (depends on 1)

The protective footwear article of claim 1 wherein the upper has a thickness of less than 2.0 cm.

### Claim 9 (depends on 8)

The protective footwear article of claim 8 wherein the thermally reflective layer is positioned throughout the upper.

### Claim 10 (depends on 1)

The protective footwear article of claim 1 wherein the opaque outer layer comprises leather.

### Claim 11 (depends on 1)

The protective footwear article of claim 1 wherein the opaque outer layer has a thickness greater than 1 mm.

### Claim 12

A method of making a protective footwear article comprising:
positioning a thermally reflective layer between an outer layer and an inner layer, the thermally reflective layer comprising an aluminized layer laminated to a fabric substrate, the aluminized layer is flexible and conformable to movements of the footwear upper without cracking or restricting movement of the footwear;
forming the thermally reflective layer, the outer layer, and the inner layer into a shape of an upper of the protective footwear article; and attaching a sole to the upper.

### Claim 13 (depends on 12)

The method of claim 12 wherein positioning a thermally reflective layer includes facing an infrared reflective surface towards the outer layer.

### Claim 14 (depends on 12)

The method of claim 12 comprising adding one or more additional inner layers.

### Claim 15 (depends on 12)

The method of claim 12 wherein the inner layer comprises a breathable waterproof membrane.
