## Abstract

Clothing and an associated method of use for modifying body temperature by transdermally modifying blood temperature comprising having a thermal device retained within at least one garment pocket substantially overlying at least one major blood vessel so as to increase the temperature gradient of said blood across said at least one major blood vessel so as to use said blood to act as a heat transfer fluid, said garment being fitted so as to press said pocket and said thermal device closely to the skin of the wearer and said pocket being arranged to be substantially aligned along the length of said major circulatory vessel while minimizing overlap across tissue surrounding said major blood vessel.

## Claims

### Claim 1

A garment comprising a fabric and at least one means to retain a thermal device transdermally overlapping at least one major blood vessel.

### Claim 2 (depends on 1)

The garment of claim 1, wherein said thermal device is actuated by a chemical reaction.

### Claim 3 (depends on 2)

The garment of claim 2, wherein said chemical reaction is endothermic.

### Claim 4 (depends on 2)

The garment of claim 2, wherein said chemical reaction is exothermic.

### Claim 5 (depends on 1)

The garment of claim 1, wherein said means to retain said thermal device is a pocket.

### Claim 6 (depends on 5)

The garment of claim 5, wherein said pocket has a pocket opening outside of said garment.

### Claim 7 (depends on 5)

The garment of claim 5, wherein said pocket has a pocket opening inside of said garment.

### Claim 8 (depends on 7)

The garment of claim 7, wherein said pocket is removably attached to said garment.

### Claim 9 (depends on 5)

The garment of claim 5, wherein said pocket is aligned substantially along the length of said at least one major circulatory vessel so as to orient a temperature modifying device along the length of said major circulatory vessel.

### Claim 10 (depends on 9)

The garment of claim 9, wherein said pocket is elongated.

### Claim 11

The method of modifying body temperature by transdermally modifying blood temperature comprising having a thermal device retained within at least one garment pocket substantially transdermally overlapping at least one major blood vessel so as to increase the temperature gradient of said blood across said at least one major blood vessel so as to use said blood to act as a heat transfer fluid, said garment being fitted so as to press said pocket and said thermal device closely to the skin of the wearer and said pocket being arranged to be substantially aligned along the length of said major circulatory vessel while minimizing overlap across tissue surrounding said major blood vessel.

### Claim 12 (depends on 11)

The method of claim 11, wherein said garment is used with actuated heat packs to delay the onset of the detrimental effects of hypothermia for the wearer.

### Claim 13 (depends on 12)

The method of claim 12, wherein said garment is used with actuated cold packets to delay the onset of detrimental effects of hyperthermia for the wearer.
