Materials, sturdyness and all that was A-ok as for what one might expect from this bag; fairly rigid, very comfortable - see others for good descriptions of its materials and feel.
But the one most important thing I couldn't find any mention of anywhere before ordering it, was that if it was tested with a 5-in-line full length bass, in my case a 5-string Jackenbacker (CBXNT DX). It fit nicely in there, even with a few centimeters to spare. That's about all I needed it to do.
Being a general size gigbag it leaves some room for the instrument to wiggle inside it, but I didn't expect otherwise.
