I'm not such a clam products fan. Their lures have failed me with broken hooks. I know of some friends with their clothes and shelters that are disappointed , durability wise.
I like your rating of 0-10 Clint.
How long have you owned the bibs ? If short term and already doing repairs, I'd give it a 4 minus just based on price.
Most things that cost upwards of a twenty bill should work as disposable in a season.
But still working as intended.
When the price goes up so does the expectations.
I don't mind spending $50.00 on a pair of lined work pants that last a few years.
It hurts and I look elsewhere when something fails short.
