The Zero-G drinking water hose is the bee’s knees. It is super flexible and folds up compactly for storage. This model has metal ends and is drinking water safe. The only challenge is that it kinks fairly easily. I prefer the 25′ to the 50′ version for just that reason, though it’s hard to turn down the 50′ length because it’s only a few dollars more than the 25.
We have used this hose fulltime for about a year now and have been extremely happy with it.
