A clothing company called HercLeon recently announced a shirt that can SUPPOSEDLY remain odor-free for more than a month, while wearing it, every day. And they say that’s true, even in the hot summer months. They say the shirts also last longer, because they’re not being washed and dried over and over again. There’s another, cheaper version for $39 that stays fresh across three days of heavy use. And one for $69 that stays fresh for 14 days.
