We'll keep this brief.

Now it's not often one gets to assess and then attempt to market a pair of soiled underpants, but, as ever, there's more to this baggy underwear than meets the eye. Which is perhaps just as well.

Travelling the world in search of the planet's most innovative gadgetry has placed one in some intriguing - not to mention diplomatically challenging - situations. And, being cautious types, security matters greatly when we're abroad. So, when travelling, we always find it helps to have a pair of stealth pants to hand.

These ultra-clever common or garden briefs are cunningly retro-fitted with a secret velcro compartment located, well, in the crotch area, in which to store one's cash, jewellery and assorted valuables.

But that's not all. Oh no. Just in case one needs to leave them lying around, these technopants have been retro-sprayed with an authentic brown stain that looks for all the world like a man-sized skid mark. Astonishing. Yet, in the world of espionage and global security, a perfectly acceptable contribution.

Simply turn them sunny side up and not even the most ardent crim would come within a hundred metres of them. Job done, if you'll pardon the expression.
