Webbing Slippage?

[Divine_Light]

I hear conflicting reports on which type of webbing slips and which doesn't.
The webbing on the AHE website says Polyester does not slip like Nylon or Polypro. But I'm sure I've heard that Polypro doesn't slip either.
Which is true?

It is stretch, not slip. Here is general rule for hammock suspension:

1- Nylon stretches too much.

2- Polypropylene stretches enough to be annoying.

3- Polyester stretches very little and is preferred.

For tree huggers, the stretch isn't as big a deal. For one, you aren't using as much and second you typically share the load a bit where it is tied off around the tree (and the stretch is proportional to how much it is loaded).

Or if you are talking slipping when using a ring buckle system, always put a slippery half after.
