The X-Bionic Trail Running Effektor OW LS Zip-Up Shirt for men creates optimal performance conditions on the entire upper body using performance-enhancing X-Bionic partial compression. This also optimizes the venous blood return to the arms and thus supports their circulation. The large, patented 3D Bionic Sphere system on the front as well as on the back increases strength. The Trail Running Effector also offers thermal and moisture regulation.
