Arm & Hammer Ultra Max Antiperspirant Deodorant harnesses the natural odor-neutralizing power of baking soda to eliminate sweat and odor at the source rather than simply masking them. Its advanced 48-hour protection formula handles demanding schedules and intense activity with ease. The invisible solid stick applies smoothly without leaving white residue on clothing while maintaining dry underarms throughout the day. Unscented and dermatologist-friendly, this formula suits sensitive skin and those seeking fragrance-free protection.
