Abstract: An underarm perspiration collecting shield that is part of the construction of an undergarment. The undergarment, designed primarily but not exclusively for men, is comprised of a front and back torso section, sleeves that cover the upper arms, and a neck opening for the head. The perspiration collecting shield is constructed of three layers. The layer closest to the wearer's underarm is constructed of material consistent with that used to make the undergarment. The middle layer is constructed of absorbent material capable of absorbing a minimum of 2 fluid ozs of perspiration before becoming saturated. The middle layer is permanently bonded to a third layer of pliable waterproof material to prevent moisture from leaking through to the wearer's clothing. These three layers, as one item, are sewn into the underarm area of the garment, extending into the front and torso sections.
