• the composite material 3 may comprise a matrix based on a breathable hydrophilic polymer.
• a hydrophilic polymer is said to be breathable if it is permeable to water vapor, but impervious to liquid water and, advantageously, if it has the property of being windproof. Such properties are particularly advantageous for a garment intended for sports.
• the matrix may be based on polytetrafluoroethylene (PTFE), polyurethane, polyester (PE), acrylic, polyvinyl chloride (PVC), polystyrene-butadiene copolymer (SBS), natural or artificial latex (polyisoprene) , or any other thermoplastic or thermosetting polymers.

More specifically, the mineral material may have a peak of radiation at a wavelength of between 4 and 14 pm when excited by visible light and placed at 30 ° C.
• Far infrared radiation can increase the skin temperature and cause a sensation of heat by being absorbed by the skin (epidermis and / or dermis) by transforming the radiation into heat.
• Far Infrared also increases blood flow to the skin through the dilation of capillaries. Oxygenation is also improved.

• the type of fabric used can be very variable.
• the fabric 2 may be selected from nonwoven fabrics, woven fabrics (warp and weft fabric), knitted fabrics (knits) and their assemblies. However, it is important that the fabric has good quality of elasticity and stretch.
• a compression garment is intended to apply an elastic force around a body part of a user.
• the compression garment generates physiological effects on its user by the application of compression on the skin.
• Compression levels are defined in different official standards (for example in AFNOR standards in France or GZG standards in Germany). Compression promotes blood flow through the veins, lowers blood pressure and reduces leg pain or heavy leg sensation. Compression increases blood flow, reduces blood volume in the veins and reduces reflux to damaged veins.
• the compression prevents the body tissues from containing too much water, promotes the drainage of harmful substances, reduces inflammation, promotes regeneration processes and improves the movement of tendons and joints.
• the combination of a compression fabric and a far infrared mineral material makes it possible in practice to improve muscle tone. This combination improves the distribution of the user's mass. The posture of the user is thus rebalanced towards his center of gravity. Moreover, this combination makes it possible to combine and reinforce the beneficial effects described above.
• the advantages of the far infrared mineral material are indeed greater when this material is in pressure with a part of the body.
• Another advantage that results is the improvement of the blood flow without a strong compression of the muscles. Indeed, too much compression causes an unpleasant feeling of the sportsman, even an embarrassment, in his movements. With this combination, one can thus obtain a good compromise with an improved blood circulation for a compression at least. This combination also results in improved resistance to effort. The athlete keeps a good maintenance of his limbs all along an endurance race, hence less fatigue.
• This type of compression garment structure is particularly effective when the combination of the compression with a far infrared mineral material is localized in a part of the body solicited during the practice of a sport of endurance and more particularly the muscles solicited during the effort. It can be the calves (via a leggings or tights), thighs and / or glutes (via a shorts or tights).
• this association By placing this association at the level of a T-shirt, it improves the posture maintenance during the exercise which avoids the subsidence of the athlete in endurance.
• this combination helps to improve the blood exchanges and thus the improvement of the functioning of the muscle (supply of oxygen, evacuation of toxins ...) .

• the standards define both a maximum perimeter and a minimum perimeter of the limb for a size indicated on the garment label.
• the tables also provide the minimum and maximum perimeter perimeters of the garment section intended to surround the limb, for each size indicated on a label. Since a compression garment is intended to compress a limb of the user, the perimeter of the limb for which the garment is intended is always greater than the perimeter of the section of the garment that is to surround it.
• the tables also include the ratios between the perimeter of a limb corresponding to the standardized indication on the perimeter of the section of the garment intended to surround the limb. For a given fabric, these ratios directly translate the compression ratio exerted on the part of the body that the fabric surrounds.
• compression of a compressive garment is determined, on the one hand, by the material of the fabric and more particularly by its elasticity and its stretch, and on the other hand, by the compression ratio defined above, namely, the ratio between the perimeter of the body part surrounded and the perimeter of the garment at that level.
