Water hose

Whoever said Zero G is spot on. I've had mine for several years and used it when camping in freezing weather. We unhook it, of course, when the temps are going below 32. As long as you don't let water freeze in it it will roll up, or fold up if you prefer, just as well as it does in warm weather. The neat thing is it takes up very little space. I had to order my 25' rv type but Lowe's has a 50' version that is drinking water safe. I have both.
