The stuff is cheap ($6, Whole Foods) and has literally one ingredient: Mineral salts. Wet your armpits a bit and rub the salt-lick rock on 'em, and your odor will be neutralized ALL DAY LONG (and it dries instantly). It truly lasts up to its 24-hour promise! Even in triple-digit temps, you'll be B.O.-free! My husband can vouch, and he has a highly discerning nose.
So, everybody, may I present, the straight-up LORD of natural deodorants! Cheers to the odor-free years ahead!
