GORE OPTIFADE Concealment is the only scientifically proven concealment pattern based on animal vision to optically fade a hunter into their surroundings. By using advanced blends of micro and macro patterns to fool animal vision rather than mimic a particular shape, GORE OPTIFADE Concealment is more versatile and more effective at getting hunters close to game.
