The chlorination of the UPD version is a game-changer. It makes the latex slightly less shiny but dramatically easier to clean and prevents the dreaded "latex stick" that tears thin skin. This cannot be overstated: the original YMD-109 was controversial. In 2015, a user in Germany required emergency extraction after the single zipper jammed and the limited breathing holes became blocked by hair. The UPD revision was a direct response to that incident.
