From the brilliant minds at Garment Guard comes our newest product, Subtle Butt. This pack of 5 saving graces effectively filters the odor caused by flatulence; Simply stick it 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.
