Abstract: A garment for aiding in ventilation of a wearer's body for relief from heat and providing a buffer zone between the wearer's body and any force exerted thereon. This garment includes a porous underlayer for absorbing moisture from the wearer's body due to perspiration and is normally worn under a non-porous outerlayer which may be attached to the underlayer. The outerlayer is separated from the underlayer by at least two layered groups of ribs. Each group of ribs includes a number of individual ribs which are spacedly positioned from each other to create channels therebetween. The groups of ribs are positioned so that the ribs of each group of ribs are layered with respect to the ribs of the remaining groups of ribs thereby creating cross-channels throughout the garment. This allows the garment to maintain a uniform comfortable temperature throughout. A pump maybe used to circulate ambient air in the channels and the non-porous outer layer may allow outward passage of moisture while preventing inward passage.
