OUR NEW 2″ WIDE HALO X2 – PULLOVER HEADBAND IS THE PERFECT SWEATBAND. LIKE OUR PROVEN X3 HEADBAND, IT WORKS AMAZINGLY WELL FOR THE HEAVIEST OF SWEATERS. THERE ARE THREE LAYERS OF DRYLINEFABRIC WHICH MAXIMIZE SWEAT ABSORPTION. THE INTERIOR SWEATSEALCHANNELS SWEAT BACK AND AWAY FROM YOUR EYES, FACE AND GLASSES, EVEN IF THE SWEATBAND BECOMES FULLY SATURATED.
