There are certainly loads of deodorant and anti-antiperspirant choices on the market. Many have great scents, but don't work terribly well. Personally, I prefer an unscented product, and absolutely need one that works well all of the time. Living in the arid Southwest United States has its pros and cons. Sweating is a con, but inevitable in our warm-to-hot climate.
Trial and error led me to Mitchum's unscented Antiperspirant & Deodorant in the Power Gel formulation. I don't care for roll-ons or products that leave that white, flaky residue on the underarms. Mitchum has that covered with their Power Gel product in spades. It goes on smooth as silk, and the applicator top assures you get just the right amount with a single pass. This is a real boon when you tally up the monthly cost of a good product.There is no noticeable scent, and the gel dries very quickly which allows you to get dressed right away and not have to worry about 'smudges' on your clothing when you slip it on.
The best part about Mitchum unscented Power Gel, though, is its lasting power. It will definitely keep you covered all day long, even in the roasty temperatures of an Arizona summer day. I spend a lot of time outdoors, even in 100+ degree temperatures, and Mitchum hasn't failed me yet. It's a great product at a reasonable price.
