Where can I find eco-friendly materials in men’s casual trousers?

I went to clothing shop two days ago to buy men casual trousers I wanted eco friendly fabric I wanted soft feel I wanted good price but I got confused fast some trousers looked nice but material was not clear some felt good but tag was missing eco info I tryed one pair and it was okay but I was not sure about sustainability I could not decide eco materials labels were very confusing for me in store shopping experience and I felt lost

Then I go to another shop in same area and I also check online including alibaba some trousers look good in pictures but real fabric is not clear I is thinking maybe online info is better but also confusing some brands say organic cotton linen hemp and recycled polyester but I still not sure what is real eco choice I want clear certification next time before buying any trousers for daily use really matter choice

Then I learn eco friendly materials for men trousers are organic cotton linen hemp tencel and recycled polyester these fabrics save water and reduce chemical use good brands like Patagonia Everlane Uniqlo Zara and Levi’s also offer sustainable lines I think eco trousers are best when comfort and earth care both matter but still I am not fully suer which brand is most trusted for daily wear do you think eco trousers are worth it I also feel online reviews help more than store labels for real truth in buying decisions
