I have not had opportunity to camp this summer for the first time in many years. MISS IT! Hope you have found yourself in wonderful places and are less intimidated about ostomy/camping concerns.
As to the cost of belts and insurance coverage - have you had your GI write a Medical Necessity Letter or call in submission for you to insurance? Sometimes it is an effective first way to get the items covered. I don't know if Nu Hope works directly with folks who need to pay out of pocket. It'd be neat if they did.
Cheers to Campers this summer!
