Charcoal underpantsCharcoal pantiesCharcoal underwearCarbon pantsThere is NO such thing as charcoal underwear. NO ONE makes underwear out of activated charcoal material. It would be very expensive. We make a pad that you can place in your own underwear.Youneed to have whole underwear made out of activated charcoal for your intestinal gas problems. A simple Activated Charcoal cloth pad (or a Flat-d) Put in your own underwear, and placed at the source of the gas is all you need. (This is the most economical and comfortable).Activated Charcoal is actually very expensive to manufacture and put in a cloth form. ***It does not last forever. It actually gets filled up with odor molecules and then does not work to absorb anymore. And you cannot wash it out of the material.There are 2 options for Charcoal Underwear-1- Underwear made out of plastic or vinyl can be very HOT and make a swishy noise when you walk. Also when the elastic around the legs and waist gets loose, it allows gas to escape because it is the path of least resistance. Then others can smell the odor.2- The other is underwear with a panel of charcoal sewn in it. This is very expensive and will only last a few weeks. (It is not true - If they tell you it will last months)(It will last a long time if you wear it one day a week)What is the difference between expensive sewn in underwear and putting a Flat-D pad in your own underwear?? NONE. And you get to use the underwear you are comfortable with. If gas goes off to the side of the panel- it still gets out of the underwear. Their underwear is not made totally out of charcoal, just a panel of it by your buttocks. It is also very tight and uncomfortable to move around in.So as you can see, the Flatulence Deodorizer pad is the most effective and economical pad that you place in your own underwear.
