Mitchum Advanced with oxygen odor control technology promises 48 hour protection. I prefer to use the gel stick but the roll on is also a great product.
Mitchum has always been known as the most effective product on the market for people who battle with perspiration, even when in school most of the 'sporty-type' girls would use Mitchum for this guarantee.
I find Mitchum to be long lasting and effective in ridding the horrid smell that can happen with perspiration. I do find though that I need to alternate deodorants as my body becomes used to Mitchum very quickly.
It is a great product and definitely lives up to its 48 hour protection name.
