I use to sweat a lot everyday, I had to change my top at lest twice a day and when I wore a sweater I had to take it off within the hour as it was all wet and smelly and in the winter when I wore my winter coat it use to get all wet in the armpit., I bought No Pong , the first day I use Bicarb Free , I went along with my day and by super time I realize I did not change my top and was not sweating or wet or smelly. Since it's winter I went out with my winter coat for a couple of hours came home and it was not wet or smelly I Love This Stuff Thank you Its been a week and everyday I am dry and no odor.,,,,only wish the No Pong would come in a bigger jar and different jar as it's hard to open with arthiritc hands.,,
