Same here adjustment is awesome, especially after time spent working out for over a year.I have a Kore belt for my go to work belt. It works well if I wear Khaki's and a tucked in shirt.
I used to wear a Daltech Bull Belt. Held up fine, still wear it occasionally but I have gotten used to the micro adjustability of the Kore. Otherwise that would be the only belt I would use.
My range belt is either the Daltech or a 5.11 nylon belt. Still trying to figure out which one works best. I like the adjustability of the nylon and that I can slide my holster/mag holders as needed.
I don't like the nylon because my holster/mag holder slides on the belt.
