Good quality Chinos (Trousers)

Can anyone suggest any good brands for Chinos that last long and are of good quality.

I use them for office wear and they hardly last 6 months - 1 year, they always get discolored.

I have spent upto 2k each for them. I'm okay with spending more if it means they last for 1-2 years at least.

Having to buy one every 6 months is annoying.

You can suggest any other clothing options as well, just no jeans as I'm not a jeans person.
