ok im kinda not sure were to put this but i figure it would go here...

i have a question about cloaks...now i know what a cloak looks like in real life but my problem is what does a flak combat cloak look like or what does a mesh combat cloak look like? does it have alot of flow to it? would you find military units using it?

Well the flak one would be quite rigid whilst the mesh one quite free flowing (till its hit). As for looks i'd imagine there's numerous patterns so it could probably vary a lot.

I see the Flak one more looking like a waistcoat and the Mesh one perhaps like a poncho

A flak cloak is likely to be segmented, so there should be some flow to it. It'd have a fabric coating and would be quite bulky.

Mesh could be concealed within a fabric, but appears a little like extremely fine chainmail. It'd be light and would flow nicely.

Modern soft body armor is not usually segemented and isn't really that bulky. We are talking about weights of less than 3 pounds for full sized male vest and the material feels more like very thick cloth than anything else. A flak cloak would be thick, it would weight considerably more than silk cloak, but it could (and probably would) be made to look like normal cloak in all other respects.

The trick is that soft body armor isn't designed to stop the bulltes flat but instead slow them down. If used as a cloak where there is naturally quite a bit of air between the first point of impact (cloak surface) and the point you are supposed to protect (human internal organs) you wouldn't even need that much material for the same effect.

Flak combat cloaks might bear similarities to the Flak Greatcoats worn by Commissars, so in essence, a trenchcoat. Mesh, as mentioned, might resemble fine chainmail.
