Hi Mineral,
I feel your pain. Dakine adjustable, great adjustment block, easy to use, but one tiny row of stitching about 5mm from the end of the webbing.
4 sessions and Plink! they come apart.
I went down to Spotlight and bought some webbing, half an hour on the sewing machine and BAM! no more webbing pulling out. Easier to adjust now too, you can change harness line positions while slogging

No idea how these things pass quality control, maybe they expect everyone to keep buying that brand once it gives out after a month. Not this little black duck.
