Trojan Magnum XL, I like the fit but haven't found it to be the strongest condom in the world, seems to break with some frequency.
Yes that point about the pores of Latex being 5x larger than the HIV virus is quite disturbing. I tend to think that latex is not simply latex, I.E. the formula of latex used to create a protective glove should not be the same as used in a condom; I would hope that condoms are formulated specifically with HIV in mind. I would expect that household cleaning type gloves have far looser requirements, and that surgical grade latex gloves would be similarly protective to condoms. I know there are many types and implementations of latex, I believe latex is technically a type of plastic elastomer (but I'm not a plastics\rubber specialist).
I do know some people who might know the answer to this, I'll see if I can find out for sure.
