• providing a second garment portion including a first vented zone, wherein a material forming the first vented zone has an air permeability of at least 550 ft3/min per ft2 measured according to ASTM D737-96 using a Frazier Low Pressure Air Permeability Machine 750, and wherein the first vented zone extends along a center back portion of the garment from proximate to a neck opening to proximate a waist opening of the garment, wherein the first vented zone is at least 12 in2, about 2 to about 6 inches wide and at least about 10 inches long, and extends along a garment wearer's spine;
• providing a third garment portion including a second vented zone formed from a material having an air permeability of at least 550 ft3/min per ft2 measured according to ASTM D737-96 using a Frazier Low Pressure Air Permeability Machine 750, wherein the second vented zone extends along a first torso side of the garment from proximate to a first underarm seam or a first arm opening to proximate to the waist opening of the garment, wherein the second vented zone is at least 12 in2, about 2 to about 6 inches wide and at least about 6 inches long, wherein the first torso side of the garment does not include a sleeve;
• providing a fourth garment portion including a third vented zone formed from a material having an air permeability of at least 550 ft3/min per ft2 measured according to ASTM D737-96 using a Frazier Low Pressure Air Permeability Machine 750, wherein the third vented zone extends along a second torso side of the garment from proximate to a second underarm seam or a second arm opening to proximate to the waist opening of the garment, wherein the third vented zone is at least 12 in2, about 2 to about 6 inches wide and at least about 6 inches long, wherein the second torso side of the garment does not include a sleeve;
• wherein the second vented zone is separate from the first vented zone and wherein the third vented zone is separate from the first vented zone and from the second vented zone,
• wherein the first garment portion, which has a lower air permeability than the first vented zone, the second vented zone and the third vented zone, forms substantially the entirety of the garment, except for the about 2 to about 6 inches wide and at least about 10 inches long first vented zone extending along the garment wearer's spine, the about 2 to about 6 inches wide and at least about 6 inches long second vented zone extending along the first torso side of the garment, and the about 2 to about 6 inches wide and at least about 6 inches long third vented zone extending along the second torso side of the garment.

A method for forming a garment for at least a portion of an upper torso of a wearer, comprising:

• providing a first garment portion which covers a majority of the upper torso and is formed of a fabric material, wherein the first garment portion has an air permeability of less than 550 ft3/min per ft2 measured according to ASTM D737-96 using a Frazier Low Pressure Air Permeability Machine 750;
• providing a second garment portion including a first vented zone, wherein a material forming the first vented zone has an air permeability of at least 550 ft3/min per ft2 measured according to ASTM D737-96 using a Frazier Low Pressure Air Permeability Machine 750, and wherein the first vented zone extends along a center back portion of the garment from proximate to a neck opening to a waist area of the garment, wherein the first vented zone is about 2 to about 6 inches wide and at least about 10 inches long, and extends along a garment wearer's spine;
• providing a third garment portion including a second vented zone, wherein a material forming the second vented zone has an air permeability of at least 550 ft3/min per ft2 measured according to ASTM D737-96 using a Frazier Low Pressure Air Permeability Machine 750, wherein the second vented zone extends along a first torso side portion of the garment from proximate to a first underarm seam or a first arm opening to proximate to the waist area of the garment, wherein the second vented zone is about 2 to about 6 inches wide and at least about 6 inches long, wherein the first torso side portion of the garment does not include a sleeve;
