I’ve been on the Ben Davis train since the 90’s and I’d say that 1 size up often does people the best. They’re work pants first, which are designed not to need a belt or sag at all. When you squat down they get tight in the butt so the bottoms pull up and don’t bunch behind the knee/limit mobility.
I do the trim fit now, which aren’t trim. Recently went up 1 size from normal and it’s a bit comfier and not really any baggier (33 vs 32, normally a 32).
Anyone try 559? I don’t find 550 that baggy, thought about them.
