ulphide and ethyl mercaptan odours at 20 times the strength of standard flatulence were continuously pumped through our carbon filter at a rate equivalent to the normal volume per second of an ordinary flatus emission. It took over 90 minutes before a single part per million was detected by a gas chromatograph on the other side of the filter. An average person expels flatulence 14 times per day for a duration of 2 seconds. These results indicate that the filter could remain 100% effective for 10 years of constant use, without washing. Washing removes any trapped odours and so long as conditioner is not used and the underwear is thoroughly dry the carbon filter is reactivated in any case.
Clearly the activated carbon is up to the job, even for sufferers of Chrohn's disease, IBS or any other digestive disorders which lead to excessively malodorous flatulence. It is the snug fit of the carbon panel that determines how effective the filtration is.
If the pants are baggy, flatus will escape around the filter and not pass through it. All of the ladies styles are equally effective with a very snug fitting carbon panel which continues under the gusset. The efficacy of the men's styles vary because flatus can escape forward of the filter in certain body positions. All men's styles are effective when standing upright or sitting upright, but the briefs are less effective when slouching or sitting with legs apart. The hipsters provide moderate support to the genitals, lifting them slightly and achieving a better fit of the carbon panel between the legs such that flatus is less likely to escape in a slouched position. The support boxers were designed to lift the genitals completely forward and this achieves an excellent fit of the carbon panel between the legs providing excellent filtration when walking slouching or sitting with legs apart. The adjustable support boxers allow the wearer to ensure that the carbon panel fits very snugly between the legs whatever shape or size the wearer is, thus giving the best filtration of all in every body position.
he men's styles offer varying degrees of support. The briefs offer the least support, although the style and supple fabric is very flattering. The hipsters do provide a degree of lift and support which achieves moderate enhancement of the genitals. The support boxers have been designed to give greater support than any other underwear and the technique of supporting the genitals with a testicular sling anchored from each hip has been patented. The support boxers lift the genitals out from between the legs and hold everything forward. Athletes like our model, Olympic high jumper Ben Challenger, find that training becomes much more comfortable as the genitals are held securely in place. Wearers comment that their package becomes clearly visible when wearing even loose fitting jeans. The adjustable support boxers allow the wearer to choose greater levels of support and enhancement. Lifting the genitals up for a long drive relieves the common problem of aching testicles. Activities such as football, aerobics, marshal arts or dance may also require greater levels of support. The adjustment enables the wearer to lift the genitals but also to decide how much to confine the package. Using the rear-most buttons provides lift but a degree of lateral movement, whilst the foremost buttons narrow the package area. This degree of control
is revolutionary; hurdlers, sprinters and cyclists would benefit from narrowing the genitals so that there is less buffeting of the testes by well developed thighs, joggers may prefer a broader platform for the genitals with slightly greater freedom of movement for example.


Mens
Support Boxers The support boxers lift a man's package forward ensuring a snug fit under the gusset which provides excellent flatulence filtration and support. This patented technique has never been seen before. Simple mechanics lead us to anchor the testicular hammock from the hip using a taut waistband and lycra sling, ensuring that everything is held prominently forward. Lifting the genitals up and forward from their usual position enables the carbon filter which continues as far forward as the scrotum to fit snugly against the skin. Flatulence odours are therefore forced to pass through it even when sitting with legs apart or slouching. Even the most malodorous flatulence will be completely filtered if it passes through the carbon filter.
Adjustable Support Boxer The adjustable boxers offer complete control over the level of support with an elastic strap which connects to the hips with button holes. The adjustable support ensures a snug fit around the gusset whatever shape and size the wearer is; meaning maximum flatulence filtration can be achieved. It is also possible to make your packet rise and fall, narrow and become more prominent depending on what you are doing varying from long car journeys, exercise or everyday social use. This adjustable method of support is also patented; nothing has been seen like it before. They are the most technically advanced mens underwear invented to date, using six different types of material and 15 separate panels to achieve optimum control.
Hipster Hipsters are a very popular contemporary style that offers good flatulence filtration and a very comfortable fit. The taut waistband and cotton lycra material provides greater support than ordinary underwear. The modal front pouch is very supple, feeling great against the skin and giving a very flattering profile. With a degree of lift, the carbon panel fits quite snugly between the legs giving good filtration in most body positions.
Brief This classic style offers good flatulence filtration so long as the wearer does not sit with their legs apart whilst flatulence is being expelled. The Briefs do offer a degree of support and the supple modal front pouch is revealing and flattering. Some men prefer briefs and so long as the wearer sits upright the briefs will give excellent flatulence filtration.
Ladies
Ladies Brief This is an everyday style of ladies brief that is very comfortable. The soft and supple modal fabric feels great against the skin resulting in a comfortable everyday style. All of the ladies styles give excellent filtration in all body positions.
Hi-Leg Brief This sexy modern hi-leg brief is revealing and very flattering as they make legs look longer and more elegant. The hi-leg doesn't quite cover the buttocks revealing a little cheek which is very appealing. Flatulence filtration is excellent in all body positions.
Shorties This contemporary style looks sporty and offers an excellent level of comfort. Their broad design makes them similar to mini hot pants and ideal for sports. Flatulence filtration is excellent in all body positions.
It is really important that you follow our recommended wash care guidelines. This is due to the construction and content of the fabrics used for our underwear.
Fabric conditioner is definitely not recommended for washing your Shreddies. This is because the Activated Carbon Cloth in the rear panel would become clogged and less effective.
It is imperative that you also tumble dry the pants on a MEDIUM temperature only or on a radiator as the carbon filter is most effective when thoroughly dry. However, a hotter tumble dry may cause shrinkage.
