Rexona Advanced Protection Sport 220mL Antiperspirant Aerosol Deodorant is specially formulated to provide men with up to 72 hours of sweat and odor protection, keeping you fresh throughout the day. With motion-activated sweat protection, this deodorant is designed to work as hard as you do. Our commitment to understanding sweat informs every product innovation. Sweat, or perspiration, is a natural and healthy process that begins shortly after birth and helps regulate body temperature. Our brains signal over 3 million glands to release sweat, which evaporates to cool the body.
