Tom's of Maine unscented Long-Lasting Care Deodorant Stick: This aluminum-free deodorant passed the test. Believe me, the test was a good one: an August day in Houston and an hour long workout at the gym! Even without any added fragrance, I smelled nice and clean all day long. If you sweat more than the average gal (or guy) does, this product may not be for you because it is not an antiperspirant (those require aluminum to be added - and this is what you want to avoid). I like this company even more after reading about how Tom's of Maine runs their facility on wind power, and in the process cuts carbon dioxide emissions by 1.5 million pounds per year - "the equivalent of planting 214 acres of trees or removing 138 cars from the road"!
