I recently bought the 1.5" standard nylon Kore gun belt. Its quality for sure, and with the micro adjustments you can truly fine tune the snugness of your belt if carrying IWB or OWB. Textured liner grips the waistband of your pants nice, doesn't want to slide or droop with the weight of the gun/holster. Directions to cut length to fit your waist size are easy to follow, and hardware for the buckle goes on easy and securely.
Its stiff, as intended to support the gun/holster weight, so if you haven't worn a dedicated gun belt with your daily wear, anticipate a transition in thinking and expectations getting dressed. You aren't going to fold up your jeans with the belt still in the loops, way too stiff for that. Belt comes off at the end of the day and hung straight.
