Ha... I just got two long sleeve medium weight Ibex T's for the gym. It's crazy when it's 75 degrees and humid outside. I keep hinting to the owner that he needs to put a lock on the thermostat, but so far no dice. There are a couple of individuals who set the thermostat in the aerobics room at 55° (no I'm not exaggerating... and who only knows the temperature of the air coming out of the vents in the low ceiling).
