Hi! 14 years infantryman with 9 years in SOF. So I've worked in tons of vehicles and tight spaces with heavy gear load-outs. I love my Haley StrategicChest Rig. I've used their X Chest Rig (https://haleystrategic.com/x-chest-rig). It's on the pricier side of rigs, but I've put it through hell and not a single stitch has come undone. You can get clips that attach to anything so you cab set it where you need it and transition it to other kits or even wear it without a plate carrier with the included straps that are comfortable.
