UnitedAttire Pro Referee Jerseys (with v-neck collar) are THE ONLY ONES available on the market with the same side vent panel that you always see on the more expensive Elite Referee Jerseys (with zipper collar). We decided to close that design gap and provide our v-neck jersey with the same side vent panel, allowing it to "breathe" better and making entire referee crew look more alike, no matter who wears a v-neck and who wears a zipper collar jersey.
