Compressport Armforce lightweight The Armforce Ultralight is a high-performance compression sleeve designed for multi-sport use. Engineered with the same medical-grade technology as Compressport’s calf sleeves, these arm guards provide targeted compression to the muscles of the forearm and bicep, delaying fatigue and improving proprioception during high-intensity efforts. Technical Performance Features Graduated Compression: Precisely measured compression stimulates venous return and reduces muscle oscillation, helping to prevent "arm pump" and soreness during long-distance runs or rides. Thermoregulation & Aeration: The 3D-weave technology acts as a thermal buffer, keeping arms warm in cool conditions while providing maximum breathability to prevent overheating as your core temperature rises. Integrated 3D.Dots: Strategically placed 3D.Dots on the forearm act as sweat-wicking "aeration chambers" and provide a light micro-massage to stimulate blood flow. Elbow Flexibility: A lighter, specialized weave at the elbow crease ensures total freedom of movement without the fabric bunching or pinching. Ergo-Fit Construction: The seamless, anatomical design mirrors the shape of the arm for a "second-skin" fit that stays securely in place without restricting circulation at the cuff.
