The Hidrofugal Classic Forte is as small as a deodorant roller. The more astonished I was that there is so little pump sprays in your pocket. Tested by me and my husband. The smell is neutral. The spray cools the skin and hardly then does not feel wet. In both the protection was 100% against perspiration odor. My husband even had jogged for an hour and though he was sweating, but the acrid smell stayed away. A reliable pump spray, which allows you to feel safe.
