Like "I know what you mean about the heat. That's why I go off the pump in the summer. I spend too much time on the beach and outside in the sun. It is too hard to keep the insulin cool. I don't have the problem, but I have said to my wife many time... "how to women wear the pump in those dresses".I don't think men have the same problem, I just wear mine on my belt. Funny thing is whe I wear my pump on mu waist a lot of people think my pump is some old fashioned pager."
