I actually really like vests to throw over armor or wear by itself. The flc is my least favorite but its not bad.
I actually liked the lbv. I know the mag pouches aren't the fastest but i like having 6 mags, 2 grenades, first aid, canteens with a cup, a buttpack for a poncho, socks, grub, etc all in one. Easy on/off, better airflow, etc
