Definitions

• the present invention relates to exercise clothing for use during exercise of varying•degrees, and has particular application to a novel ensemble of clothing for use in exercise.
• the term -'exercise is intended to embrace any vigorous activity whether done for recreational purpose or for physical conditioning or in sport competition.
• the design of exercise clothing was concerned primarily with the desirable selection of fibers, the proper selection of fabric construction, and the design of the garments to provide the desired degree of freedom for body movement.
• the outerwear is made of waterproof fabric or at least water-resistant fabric so that it sheds water and prevents the weather from wetting out the exercise clothing underneath. For less severe weather, a fabric which simply sheds water will often be used in place of the waterproof fabrics which tend to become clammy when worn during exercise.
• the body has physiological processes for seeking to maintain a uniform body temperature by generating sweat or perspiration when the body is hot, and providing a protective air layer by the use of "goose bumps" when the body is cool.
• sweating does not provide sufficient cooling
• the body reaction increases heart activity to pump blood into the capillaries adjacent the skin to assist in reducing the skin temperature.
• Shivering is also a physiological reaction which generates body heat through activation of the muscles. In any case, the body reaction saps energy and increases the fatigue resulting from the exercise activity.
• Underwear is designed to accommodate to the physiological reactions of the body.
• the most comfortable underwear utilizes a cotton fabric which absorbs moisture and allows it to be dispersed over a wide area to accelerate evaporation and cooling. The dispersion of the moisture through the cotton fabric provides a comfortable undergarment which may be worn next to the skin without itself creating discomfort by reason of its confinement.
• a winterweight underwear fabric which provides a high comfort level by reason of a combination of cotton fiber, bulked yarns, and a fabric construction providing air pockets which not only provide an insulating dead-air space but also permit evaporation of moisture, thereby increasing the comfort level provided to the individual wearing the garment.
• the thermal fabric of U.S. Patent No. 4,797,311 has been improved by being knitted of a hollow-core polyester fiber identified by E.I. du Pont Co. as
• the inner and outer surfaces are characterized by air-entrapping cells formed by channels and ribs and transfer of moisture between the inner and outer surfaces by wicking through the fabric.
• the present invention provides an assembly of garments which combine to minimize overheating of the body during exercise so as to stabilize the body temperature at a comfortable level.
• the novel ensemble of garments enables the body to be protected from the elements during exercise without causing excessive overheating.
• the invention utilizes multiple layers of clothing and accommodates maintenance of the desired body temperature by arranging the garments in the separate layers so as to effectively allow dispersion and dissipation of body heat, avoiding the need for the body to divert its energy towards temperature conditioning of the body, as by the normal physiological reactions to excessive heat or undue chill.
• the present invention provides a system of clothing which may be worn during periods of exercise to enhance the maintenance of the proper body temperature without triggering excess physiological reactions.
• a significant component of the system of the present invention resides in the provision of a novel body garment, i.e. underwear, which cooperates with outer garments to facilitate the distribution and dissipation of body heat.
• the novel undergarment of the present invention provides a garment which lies close to the skin. It may have a napped surface of bulked yarns providing a layer of trapped air.
• the fabric is a modified 2 1 rib providing a knitted framework of hollow-core polyester fiber which wicks moisture from the trapped air and distributes it through the fabric.
• the garment is characterized by venting patches adapted to register with the body joints where hot spots may occur.

• This patent describes a cotton fleece fabric having a jersey outer surface and a fleece inner surface having the stretchability inherent in knitted fabrics but which has limited residual shrinkage.
• This fabric is suited for use as an insulating layer because of its comfort when worn and the insulation provided by the fleece inner layer.
• Another fabric is a dual-ply fabric designed to have 360° stretch without torquing or puckering.
• Such a fabric is made in two interconnected plies with the fabric of one ply having an S-twist core spun spandex yarn wrapped with hollow core polyester fibers, and the back with a similar yarn but made with the opposite twist so that in finishing the fabric, the front and back plies may be controlled to set and maintain the courses and wales substantially perpendicular to each.
• the use of the spandex yarn wrapped with the hollow core polyester provides a high level of insulation, and the hollow core fibers permit wicking of the moisture from the inside of the fabric to the outside, thereby dissipating any build-up of heat and moisture within the garment.
