Temperature rise is a very troublesome thing for a doll. It is very uncomfortable to wear it when you are sweating and soaking wet. Sometimes it's even worse when too much sweat flows into your eyes. I can't see anything clearly, and I can't wipe it right away. Basically, a sweaty boy like me, going out for a cruise is no different from taking a shower. Girls may be better, but no one is spared when it is really hot.
