A number of sophisticated technologies, such as the 3D BionicSphere® System, make the X-Technology Swiss wool intelligent, so that Apani Merino cools, warms and dries naturally. The result is an ecological product with a fine yarn, spun in Germany and made of only 18.5 micrometre thick Saxon-Merino wool. The combination of elastic and natural components guarantees a high degree of stability and comfort. It features a 3D system of high-tech fibres on the chest and the back, which maintains a thin film of sweat on the skin to support cooling.
