Fabric is much lighter weight. I put them on straight out of the bag. They were snug a snug fit compared to the same sized Indigo Bibs purchased on the same order.
I and i just had the lower side buttons buttoned, and after about 10 minutes, I sat down a couple times and the fabric next to the buttons ripped about two inches long.
I have 3 other pairs of Dickies Bib Overall... same size... heavier denim... no rips. Gonna take them back.. Hopefully I can get a refund...
