My Shreddies Men's Flatulence Filtering Boxer Shorts

There's a reason the My Shreddies motto is "Fart with confidence." Because that's exactly what these support boxers give you — the freedom to go about your day without a second thought about wind, odour, or embarrassment.

The My Shreddies Support Boxer is the premium style in the men's range — and it does more than just filter flatulence. The supportive, close-fitting cut maximises odour filtration by keeping the activated carbon panel firmly in position, while also enhancing the profile of the package area. Confidence on every level.

The closer fit isn't just a style choice — it's functional. The more securely the garment sits against the body, the less chance there is of gas escaping without passing through the carbon panel. Better support means better filtration. Available in Black only.

Made with Zorflex activated carbon fabric — the same cutting-edge material used in chemical warfare protection suits — My Shreddies support boxers trap and neutralise flatulence odours completely before they can escape. They look like premium boxer shorts. They feel like premium boxer shorts. Nobody knows you're wearing anything different.

The science that makes it work

Sandwiched inside every pair of My Shreddies is a layer of Zorflex — a highly porous activated carbon cloth that absorbs and neutralises odorous gases on contact. The carbon's porous structure captures organic and inorganic molecules the moment they pass through, eliminating odour at source rather than masking it.

Zorflex is used across medical, defence, and industrial applications worldwide — in protective clothing, decontamination equipment, and chemical, biological, and nuclear hazard suits. It is the most effective protective fabric material available. And it's now quietly working inside your underwear.

The clinical evidence is unambiguous. Research published in The American Journal of Gastroenterology found activated carbon underwear to be the most effective method of eliminating flatulence odours. Independent testing by De Montfort University confirmed that the Zorflex fabric:

"The fabric was found to remove ethyl mercaptan and sulphide so effectively that it can filter odours 200 times the strength of the average flatus emission."

— De Montfort University, 86th Textile Institute World Conference

Two hundred times the strength of average flatulence. Completely eliminated. Whatever your symptoms, My Shreddies handles them.

Who they are for

Excessive wind is a common and distressing symptom of many conditions — and one that significantly affects confidence, social life, and quality of life. My Shreddies support boxers are designed for men living with:

• Irritable Bowel Syndrome (IBS)
• Crohn's disease
• Ulcerative colitis
• Dyspepsia and gastritis
• Diverticular disease
• Constipation
• Coeliac disease and gluten intolerance
• Lactose intolerance and other food intolerances
• Post-bowel surgery digestive changes
• Gastric bypass and bariatric surgery
• Excessive sweating alongside digestive symptoms

They are also worth considering for anyone who simply experiences embarrassing wind in social or professional situations — you don't need a diagnosis to benefit.

Zorflex — what makes it exceptional

Beyond odour filtration, Zorflex has properties that make it genuinely comfortable for all-day wear:

• Sweat-resistant — stays fresh even during physical activity
• Antimicrobial — naturally inhibits bacteria
• Lightweight and breathable — you won't notice it's there
• Liquid repellent — stays dry and comfortable
• Flame retardant — a quality standard that reflects its military-grade origins

Comfort, fit and sizing

My Shreddies support boxers are made from 95% cotton and 5% elastane with a 100% activated carbon lining — soft, supportive, and comfortable for all-day wear. The supportive cut keeps everything firmly in place, maximising both comfort and filtration performance throughout the day.

Available in Black only. Sizes based on waist measurement:

• Small — 76–81cm / 30–32in
• Medium — 84–89cm / 33–35in
• Large — 91–97cm / 36–38in

Washing instructions — important

The carbon filter reactivates with every wash, meaning your My Shreddies work as effectively after 100 washes as they did on day one — provided you follow these instructions carefully:

Important: Machine wash at 40°C maximum. Tumble dry on medium heat. Wash with Soda Crystals only. Do not use fabric conditioner, bleach, or dry clean. Iron on medium heat if required. Follow care instructions and the filter remains effective for the life of the garment.

This is the one rule that matters. Get it right and your My Shreddies will last for years.
