Looking for Durable Alternatives to Black Diamond Notion Pants

I bought Black Diamond Notion pants because I liked their clean look. I could wear them to the office and then go climbing without needing to change. I work in a pretty casual office, so as long as I don’t come back drenched in sweat, I can work in my climbing clothes, which is something I really appreciate. However, my Black Diamond Notion pants have an unfortunate tendency to wear out or tear at the crotch area. The seams hold up well; it’s the fabric that rips. I’m attaching some photos.

I’d love to know if anyone has a good alternative suggestion.
