Having worn a few myself in other venues, the dank smell is also unbearable. And don't you dare rip one while inside, else you'll be friends with the fumes, for a quite a while.An old CM told me they could wear ice vests offered to them however the heat would melt the ice quickly and they'd end up with warm water swishing around them so many decided to just tolerate the heat instead. They'd lose quite a bit of weight also in the first week or so.
