Also model.
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.
I'm pretty fond of the Tru-Spec 24/7 design, especially in ripstop.
I have/had some 5.11s (the ones I had were a cotton that really retained moisture, the pocket layout is more obtusive than it is useful, and their waist elastic is the kind that makes mark-leaving bunches), a pair of those Vertx ones that try to hide the cargo profile (always found them a bit uncomfortable, also bunch-type elastic), some of the Duluth "Fire Hose" (great for manual work, too heavy and hot for casual wear), one pair of the tru-spec in cotton (pretty good)... And multiple pairs of both pants and shorts of the ripstop tru-spec 27/7 because they have a really nice waist elastic design, a pocket design that is actually useful for retaining stuff and tries to minimize profile when empty, the fabric breathes and dries well without feeling plasticy...
They slightly changed the interior of the pocket design a while back and it makes the retaining flap not quite accept my particular phone and adds an extra layer of fabric and hence added bulk/lost breathability to make an additional slot, which was unfortunate, but still, highly recommend.
