Carhartt Men's Rugged Flex Rigby... https://www.amazon.com/dp/B07QCWD8VB?ref=ppx_pop_mob_ap_share I’ve been wearing this style for casual use and they’re super comfortable while staying durable and lasting a while. I wear a 35x30 and it took me like 6 tries to find the style and size that I wanted. I’d highly suggest using something like Amazon where you can return easily or going to try them on in person. Carhartt does have a “force” line that’s more like canvas and coils definitely be suitable for hiking. I had a pair of those and they didn’t breathe very well so I tossed them… I was also working in the Middle East with crazy heat too though.
