Thanks Alex, Andrew and Adam. Hmmm, AAA Ć¢ā¬ā¹ !
It is quite flexible Adam. The idea of those back supports is to have them loose when you're walking around, then pull them up tight (the whole belt is velcro) when you need to bend or lift. I have it sitting quite snug - not so it flaps around under the armor, but not so it's too tight that causes tension. And with the shoulder straps, it can't fall down.
First 2 troops have been great. Troop 1 - had troubles with the calf closures. Ended up swapping out for Velcro. I just couldn't get the hooks right. Too tight, I couldn't get them on or off. Too loose and they kept coming undone. Troop 2 - no problems whatsoever, no loose bits, no bites, really comfy. Not quite "sit down comfy", as comfy as TK armor can be I think.
I am pleased I re-did the bicep and forearms. Looks so much better. Thanks.
