Where can I buy eco-friendly outdoor pants made from sustainable materials?

I visited an outdoor clothing shop to find eco friendly pants two days ago. I wanted something sustainable and strong. I also wanted safe materials. But when I checked the pants I felt disappointed. Most were not eco-friendly. Some looked weak and cheap. I could not trust them. I could not decide confidently.

Then I visited another shop in the same area. Some pants looked better but were expensive. Some were affordable but not sustainable. Some seemed perfect at first but material was unclear. I remembered I used clothing before that lost quality quickly. That made me hesitate even more.

To check more variety and options while scrolling many online marketplaces including alibaba I found many eco pants. Some looked sustainable and durable. Some were simple and low price. Some had better materials and comfort. There were many options available. This made me excited but also confused again.

it feels that I go out of mind when I have huge number of options. Now I am thinking should I trust eco products online or local stores for real sustainability? What would you do in my place?
