Men's Under Layer Singlet Vest
How good you feel during sports is decided directly on your skin. Because that’s where 90% of human heat regulation happens. And that, in turn, is why X-BIONIC® engineers developed the intelligent X-BIONIC® INVENT® 4.0 LIGHT SINGLET for men.
This underlayer for warm weather uses thermoregulation to counteract the risk of overheating. When worn directly on the skin, it produces its climate-control effect. The integrated, patented and award-winning 3D Bionic Sphere® System cools when you sweat and warms you when you're cold. Wear it during running, cycling, trekking or any other sporting activity.
Feel more powerful and enjoy a consistently comfortable temperature. Sleeveless, comfortable on the body and with an advantageously thin structure, this singlet can be worn under your sportswear without adding unwanted weight. You get exactly what you need from it: the cooling effect you want on warm days.
