Sports mesh with polypropylene. Technical and functional garment that offers excellent moisture management and light compression to support muscles and reduce muscle fatigue. Sweating is our body's natural cooling system. Technologies: -3D technology provides the athlete with a feeling of comfort by cooling them during exercise and warming them during recovery. Thermoregulation occurs when the body's temperature increases and it begins to sweat. If there is no sweat, the system serves as a thermal insulator. The technology of this garment means there is no sensation of sweat in the armpits, as it allows perspiration from the first moment thanks to the use of heat convection properties for its evacuation. The fabric is folded according to the accordion principle, ensuring that the winter cold does not chill your elbows. Even when folded very tightly, the insulation effect is maintained through the warm air stored inside. The elasticity of the fiber allows freedom of movement without friction. Even in sports with continuous movement, such as trail running, it does not produce symptoms of muscle fatigue with movement. The constant movement of air along the duct also effectively removes moisture from sweat areas. Improved performance due to gradual compression that reduces muscle oscillations. It has a fine 3D fabric that adapts completely to your skin without rolling or shifting, preventing chafing. Thermoregulator It is made with high quality material, making it a resistant and highly durable garment. Protects against ultraviolet radiation. OEKO-TEX certified: Free of harmful substances and antibacterial. Made in Spain.
