About Shreddies

Shreddies contain activated carbon cloth sandwiched between layers of regular fabric. The specialty layer absorbs and traps the odour before it can make its way out into the open.

How They Work

We and are proud to deliver a product to the Australian community which has proven to have a positive impact on people’s lives including improved health, relationships, and social and community engagement.



Shreddies flatulence filtering garments feature an activated carbon back panel that absorbs all flatulence odours. Due to its highly porous nature, the gas becomes trapped and neutralised by the cloth, which is then reactivated by simply washing the garment.

Previous research published in The American Journal of Gastroenterology found activated carbon underwear to be the most effective method of removing flatulence odours. The garments have gone through rigorous testing, and findings from research by De Montfort University were presented at the 86th Textile Institute World Conference; the fabric “was found to remove sulphide and ethyl mercaptan so effectively that it can filter odours 200 times the strength of the average flatus emission.” The fabric remains effective for the life of the garment providing the care instructions are followed correctly. The Shreddies motto is ‘Fart with confidence’ and our garments ensure just that.


Shreddies can be worn by anyone but they offer the perfect solution for treating excessive gas issues caused by IBS (irritable bowel syndrome), Gastritis, Crohn’s disease, Dyspepsia and Colitis as well as food intolerances and many other bowel and digestive disorders. Shreddies product range includes pajamas and undershorts which can be worn over incontinence products, to stop continence related odors from escaping. Anybody that suffers from excessive gas or odours caused by incontinence will know of the social issues that it can cause, Shreddies not only improves the physical symptoms but also helps to reduce the anxiety associated with this condition.

In many cases, simply not having to worry about gas can help improve a person’s condition. Anxiety can create chemical changes in your body which can affect your digestive system, exacerbating a person’s condition.
