I came accross this very interesting article.

Can camera's really see through thin clothing?

I found it funny because In Australia, female perves are becoming more and more as men's SPEEDO'S and briefs are getting thinner and thinner.

Really, I have no idea how people are turned on by such acts as trying to peep through people's clothing.

Scantily-clad female athletes like this one will now be protected from see-through photography — that is, that very minimal skin surface that isn’t yet exposed.

Sports equipment manufacturer Cramer Japan is releasing a line of infrared-proof underwear, the first of which is Shot Guard, to prevent enterprising perves from taking see-through snapshots of female athletes.

In recent years, there has been an increase in the number of people using infrared light to take sneak see-through photographs of female athletes and children at school sports events. Sporting groups and school officials have raised concerns about such photography.

Some swimsuit manufacturers have already released products that block out infrared rays, but there have also been calls for the introduction of protective clothing for other sports.

Cramer Japan introduced its products after being approached by the Inter-University Athletic Union of Japan over the problem.
It spent two years developing the clothing with textile manufacturer Toyobo, and Toyoshima, a wholesaler and trader of fabrics.
