I have problems with my double knee tree climber pants. I have had success with arborwear in the past and have quite a few pairs of pants but I have one pair that the stitching has gone to crap. I haven't worn them that much and the crotch has been restitched on the zipper but now the whole crotch is starting to cut loose as well as the back pocket is coming undone. I know tree work is tough on pants but this particular pair is just falling apart and still looks pretty new. Has anyone else had these problems with any of the pants? I know treerat had some issues with his a while back. Maybe this was just a bad run or something I don't know.
