Today BRUT is still one of the best-selling men's fragrances. A Brut man will never let you down. Brut products first launched in 1964 and currently rank among the top 3 men's fragrances sold in mass. Underarm odour is caused by the by-products of bacteria that thrive on sweat. Brut antiperspirant/deodorant sticks with trimax prevent odour by stopping the wetness and killing the bacteria, leaving only the clean, classic fragrance of Brut. The trimax formula fights odours in 3-ways. Trimax uses two anti-microbial agents to eliminate the bacteria that cause odour plus uses the fresh scent of Brut to leave you smelling great.
