I thought this thread was about the harness worn to keep the hose close to you, and it probably is because it isn't phrased very well.
The best and most verastile harness i have found is washing line type nylon rope inside a length of garden hose.The benefits are.
It's strong
It doesn't dig in around the neck and shoulders
It's high vis worn sash style to keep the hose tap handy.
It can be cut to any lenght
We all have plenty of it
