Slider harness

[Mango Birkie]

I have seen only a couple of fleeting references to the Slider harness.

Has anyone here had experience with them? The BG isn't bad, but the length adjustment is constantly slipping.

I use one on bari . It is by far the best for weight displacement for standing up. However I find it is restrictive when I am sitting. I play standing mostly in our quartet and would recomend this as very comfortable for long sessions.
