I have not had too many pairs make it to "wearing out". They are using falling apart before then. In this case is was the multi-part chamois becoming unbonded. However, most times that my bibs fail young is due to threading coming undone, usually around the chamois. I will admit that I wash my bibs in the washer (on gentle cycle). I do not use a dryer on them. In one recent case I had a pair of high-end bibs (I wont mention the brand) that are often touted on this board. After one season the threading around the chamois become undone. The company fixed them under warranty. They made it about halfway through the next season (in rotation with several other pairs) before the threads gave up again. I had them fixed again (no charge) this winter and have used them once this season so far with no issues. While its great they fixed them under warranty that should not have happened in the first place. Ironically I have some low end Giordana and Performance bibs that I've had so long I cant remember and they've held up great, although they are not as comfortable as my higher-end bibs
