Active or resting, the “Dainese Undergear” supports the body in any situation maintaining the optimal temperature of 37 °C. It cools, when you sweat, and warms, when you freeze. The intelligent “3D-BionicSphere®” system on the chest and back leaves a residual moisture on the skin, which evaporates and cools. “SweatTraps®” transport excessive sweat directly to the outside. If no sweat is present, then a unique process uses air heated by the body as thermal insulation. The accordion principle of the “ExpansionRibs™” keeps knees and elbows pleasantly warm, even when bent.
