So I was on the way to the gym last week, I threw my ball bag in the car. Keep in mind it was bloody cold outside...and when I say bloody cold I mean -30C. Well my commute took longer than usual due to traffic and when I got to the gym my balls were very cold and di not bounce. I proceeded to warm them up by playing pepper and eventually just hitting against a wall, they soon warmed up and were fine. But my tachikara 5WSC went flat when it warmed up. I refilled it and played with it for another 3 hours or so. Next day it was flat again...now it won't hold air for longer than a day.

I also have an old school nike beach ball and an older baiden one but they seem to be fine. Does it possibly have to do with the loose bladder construction of my tach ball? Is there anything I can do or am I pretty much just screwed? Sometimes up north here it is very difficult to keep your balls warm
