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.
