C/A: CCM Premier 1 Bernier pro return - P1 body with X-Pulse or Gatekeeper arms and back. I added a tie down on the inside of the chest pad. It's similar to what you see near the belly button on the front of all C/As. Also added some extra rib protection with some air pillow pieces I found off an old set of pads.
Pants: Vaughn Vsomething. Maybe V4 or V5. Added an inner belt myself.
I wear pants semi loose outside, snug inside. No suspenders. Lace my pants through the nylon tie down I created on the inside of the chest. C/A sits outside my pants.
No issues - wearing my chest on the outside creates a nice air cushion for pucks to die in. Collar on the C/A hangs kind of low, but I wear a Maltese combo underneath to cover.
Happy to post pictures if you need them.
