Those look like they flex real well. Although i have not worn the new type of these i can tell you to watch out for the liberty denim rigid as i attempted those and after wash they shrunk and got white spots all over and had to complain to kohls for a refund. I now wear carharrt wip, Levi’s or peviani overalls.That said you should be fine with these.

These meaning the liberty flex as they are not denim rigid.

The carhartt buckles are so hard to twist and hook. It looks like the liberty has a buckle like my oshkosh bibs have. I wish oshkosh would make adult bibs again.

Liberty has buckles like osh kosh and wish osh kosh made overalls again as id totally wear. Now with respect to carharrt wip they also have buckles like osh kosh and bought two pairs. The regular carharrts are the ones that hard to twist. This is what carharrt wips look like and note i either wear these or levis and generally only wear overalls. https://us.carhartt-wip.com/products/bib-overall-denim-blue-stone-washed

I also liked osh kosh. They were my first pair of bibs i had as a young teenager. Wore the all summer on the farm.

My first pair was old navy and then dickies in my teen years. Now i wear levis, carharrt wip and peviani. I stocked up so i only wear overalls and nothing else.

That said I wished i tried osh kosh though. Shame it no longer exists for men.
