Speed Stick is an American brand of deodorant/antiperspirant produced by multinational healthcare company Colgate-Palmolive. It was formerly known as "Mennen Speed Stick" prior to Colgate-Palmolive's purchase of The Mennen Company. Currently, the products feature the words "by Mennen" in a small font on the label. 5.0 out of 5 stars It works! It keeps me fresh smelling all day with no irritation. It great to find an affordable aluminum-free deodorant option. I switched from the regular speed stick to this aluminum free version and it took me about a week to stop smelling funky.
