X-Bionic Twyce Arm Sleeve

Run more efficiently without overheating! TWYCE 4.0 RUN SHORTS WOMEN from the X-BIONIC® 4.0 generation offer you the largest cooling surface of all X-BIONIC running shorts. They perfectly equip running enthusiasts to maintain high activity in warm weather. Your first advantage is the patented, award-winning and unprecedentedly effective ThermoSyphon® System, the next generation of the 3D Bionic Sphere® System at the front. Its complex 3D structures and Y-shaped elements maximize air exchange. It cools when you sweat and warms you when you're cold – and it achieves these heating and cooling effects faster and more efficiently than ever. Your second advantage: this precisely crafted functional wear for runners is manufactured in Retina® ultra-high-definition quality. You can feel the difference in the highly effective density, the intensive functional transmission and the precisely defined functional zones. The shorts include a practical back pocket.
