I still fel that placing it in the dryer removes some of the adsorbed odor rendering the garment useful in reducing some of the human odor we produce . It is however just one piece of the scent control puzzle. No, it won't stop a fart, and you can't sweat all day,throw on a suit and expect it to work miracles. All aspects of scent control are important including playing the wind. I wait until I find the product on sale and then purchase it . I'm happy with the performance so far and plan to replace my suit in the near future!
