A US underwear company have invented special pants to save the embarrassment of flatulence sufferers.
The pants have a built in filter and airtight fit to ensure the elimination of nasty odours.
Makers Under-Tec say the "gas eaters", officially called Under-Ease, are no joke but a "serious product that serves a purpose".
They say the pants "relieve the pain without the shame" and "improve social confidence".
The pants are designed to be airtight thanks to elastic around the waistline and legs.
The "core technology" of the product is a pocket with a replaceable filter inside.
The multi-layered filter is made with the two outer layers of wool felt, two layers of non-woven polypropylene and spun glass materials.
In the center of the filter is a single layer of activated carbon.
Inventors have found the filter cuts bad odours.
The pants are machine washable and last several months depending on use.
They can be worn anytime and anywhere – although they are not recommended for use in a swimming pool or hot tub.
Happy customers on the Under-Tec website include sufferers of Crohns Disease and Inflamatory Bowel Syndrome.
In testimonials on the site, satisfied comments include: "Thank you. You saved my life. I can now go to school without worry" and "they really are working for me, an answer to my prayers because I like to wear them when I go out."
