Hanging low, definitely!

If they're up, they'd be OK for kicking, but as I've mentioned in my other posts I prefer lots of other ways than just kicking.
If they're up, I'd grab your sack between your balls and your body and squeeze them out where they're more exposed and vulnerable. Or else tie a little leather belt or rope around your sack to be able to whack away at your nuts however I wanted to.

If the temperature is warm enough, they'd be hanging low enough anyway.
Hanging loose. And bare.
