I normally carry a backpack because I like having some extra inventory slots for things like my wireless headphone case, pen, notepad, and occasionally a portable charger but I have been wearing a pair to work and quickly realised how capable they are for a majority of what I do.
Ideally I'd like something relatively durable maybe with internal pockets or organiser loops to hook a pen to.
I feel like I recall Rotcho and 5.11 selling cargo pants but I don't know if they are as good as some of their other products.
The ones from Duluth Trading are solid, and are actually comfortable. The Flex Firehose ones repel water pretty well, but do get hot and muggy inside when out hiking. Nice for typical days though, esp in the cooler seasons.
