I had a bathing suit now in operation since September 2009 and a few days ago, ie in March 2012 landed in the trash. If they survive had about 500km / year, most of it in chlorine-containing water in the pool (ie rather little UV influence). That is, it has been with me about 1200km and absolutely no complaints, of course, it is already significantly affected by more than 2 years from the chlorine, which is why it was also singled out. In summary, I am extremely pleased with the trunks that the material for about 2 years yields in regular use is fully okay. So I can only say that I have my next byor Arena swimsuit already ordered :)
