Good potable water hose?

I buy garden hoses that are designated "drinking water safe" or "potable water safe". They make them but you often have to order them online. I use the thicker hoses because I make my own insulated heated winter water hose. I also buy the hoses in much longer lengths and cut them into several different lengths (long, medium and short) and put hose menders and quick connects on the ends. It allows me to have a hose of the length I need without having a too long hose curled up. I store hoses in Christmas wreath storage bags. Neoprene foam insulation allows the hose to be curled up tighter than the polyfoam pipe insulation.
