Poor quality materials and poorly made. Provides practically no support for the funnel, and the thick spandex gusset is both uncomfortable and absorbs and holds moisture. Honestly I don't even use the gusset, it's redundant and gets in the way. The leg straps are long, even fully shortened I can put one around my chest with length to spare. The elastic is soft, it stretched, buckled, and was ruined by the 1st evening. Had to tie them so there'd be at least some support, but this is uncomfortable and further damages the elastic. The clear strap is flimsy, I was worried it'd break every time I adjusted it. The harness feels like it'll fall apart in the wash. I can't recommend this harness. Cool concept though, being mounted behind the packer rather than around the shaft, just needs work and care put into the execution

Great to have an extra. I will probably get one more at some point.

Not great material - ones on photos look higher quality. I cannot imagine it lasting long before splitting or being over stretched.
