Flatulence Underwear

Farty Pants

  • Absorbs and neutralises those unwanted trouser fumes
  • Trump away on the old gluteal tuba to your (f)heart's content
  • No need to clench and hold in that uncomfortable trapped wind
  • Harnesses the same technology found in chemical warfare suits
  • Capable of stopping smells 200x stronger than the average guff
  • Prevent those horrific crowded elevator moments


Some people say that flatulence should be seen and not heard. These people are clearly very confused and probably already wrestling with their own horrendous southerly vapours. Farts should be heard and not smelt, and arguably not even heard.

Flatulence Underwear allows you to finally trump with confidence, safe in the knowledge that those unwanted trouser fumes won't sting the nostrils of anyone nearby. These ordinary looking undergarments contain a highly porous carbon back-panel, so the next time there's a roar from the rump, the odorous vapours become trapped and neutralised by the cloth.

Harnessing the same technology found in chemical warfare suits, these powerful pants are capable of stopping smells 200 times stronger than the average fart. If they're good enough for Mustard Gas then they can easily handle your full-bodied and intriguing stenches.

Everyone knows someone with obnoxious wind habits – a bona fide bench-warmer, a fragrant and shameless one-man jazz band. Or perhaps you are the one guilty of blowing the old bum bugle a little too frequently? Whoever it is, they can pull on these gas-trapping pantaloons and trump away to their (f)heart's content.

Please Note:
  • Tumble-dry on a low/medium heat
  • Never assume that a trump is simply a trump – this is not a nappy
  • Particularly terrible diet? We'd recommend trying two pairs
  • Active carbon back-panel is reactivated during washing
  • If you're unsure of size, it's better to be too tight than too loose. The last thing you want is to spring a gas leak

Customer Reviews

Bought these for my hubby - naturally! Super comfy, smooth and rather effective. Thank you to the inventor of this genius product. Sharing a bed with him (my hubby, not the inventor!) is now safe, quiet and odour free. Splendid!
