Have you clicked on the Ad for 'Hot Pants'?
As a chunky of thigh person, I thought they sounded interesting, so clicked on the banner (sounding like a spammer now).
I have to say they sound horrific -"They essentially work by increasing your perspiration by up to 80%" Eurgh!
Personally I've never felt the urge to increase the amount of sweat produced by my arse and groin.
