For this accessory the “wallaby” (kangaroo) serves as role model. Licking frequently its forearm this animal cools its blood and so its whole body. Correspondingly special hightech knitting-structures and the patented 3DBionicSphere® system widely disperse the perspiration in a film over the skin. Cooling occurs by evaporation which contributes to keep the body temperature at the optimal 37 °C and therefore, powerful. For a turbo effect you hold the X-BIONIC® Wallaby into cold water and thus enforce the cooling mechanism.
