X-Bionic's ENERGY ACCUMULATOR 4.0 PANTS are designed to maximise performance and endurance, even on long days on the slopes.

Thanks to cutting-edge technology built in, these trousers regulate body temperature to maintain a stable 37°C, keeping you cool when you sweat and warm when it's cold. Made from a lightweight fabric of 90% polyamide, 5% polypropylene and 5% elastane, these trousers weigh in at just 180g. They feature high compression (4/5) and robust insulation (4/5), guaranteeing exceptional support and comfort.

RETINA® technology provides ultra-precise definition, while the 3D Bionic Sphere® system with ThermoSyphon® ensures effective thermal regulation thanks to complex internal and external air structures. The IDEO-WAISTBAND waistband is ergonomically designed to stay in place even with constant movement. Skin Nodor® yarn helps prevent odour and bacterial growth, keeping you cool even after strenuous activity.

Made in Italy with Swiss engineering, these trousers have won over 700 international awards and 800 patents.
