hmm I have had a set of FI Mille Assos bibs for about 10 years, I have several pairs but that pair is one of the oldest and gets used and washed about once a week after 2-3hours of use all year round, so around 500 times in the laundry, and now it's starting to show a few signs of wear... But we don't have chlorinated water in Sweden, so maybe that's the reason.
