We've come across a lot of interesting products over the years here on The Flint Skinny. This one may be close to the top for level of absurdity. I don't really like the description of something being imprgnated, even if it is just fabric, anywhere near a ladies underwear. That said, I am really curious if they work.
Subtle Butt, 5 pieces -$11.95
Problems with smelly gas? This pack of 5 saving graces (also affectionately known as fart pads or fart filters) effectively filters the odor caused by flatulence; simply stick one in the right place and you're ready for a chili cook-off.
Each 3.25" square filter is made of soft fabric with an antimicrobial treatment on the side touching the skin. The fabric is impregnated with activated carbon, which faces the underwear or the pants and has a vast surface area for bad odors to adhere to and get neutralized. Two adhesive strips are strategically placed so you know which side is which. And at around 1/32" thick, you will never know it's there. Now with improved adhesive!
