The Gruv Gear Solostrap Neo 4” is very comfortable.
One thing to keep in mind is that it’s slippery, which can be a little problematic if your bass is susceptible to neck dive.
It’s also relatively short, so consider getting the extension if you are tall. I’m a long-bodied 6’2” and without the extension I have it at its longest setting to achieve a waist-high bass position.
