This has been on my mind for a long time, cloting layers! Yes. Here's how I think it could work; for storage purposes it could be designed so that you could "attach" lower teir cloth to those that would be on the outside layer. I.E. A t-shirt would attach to a checkered shirt which could attach to any outer wear (rain coat, jacket, etc.) The storage slots would expand and your heat index would go up. Alternatively if players were "heating up" they could "detach a layer (at the cost of those expanded item slots) and therefore reduce their heat; this could be scaled all the way down to just wearing a jacket with nothing underneath. How does that sound?

A good suggestion, or hey why not just allow characters to wear both the plate carrier and the smersh vest?!?

All programming an coding aside, there was a time that the smersh was wearable with the other vests when it was implimented in the first experimental branch. Historically the smersh is wearable with most assault and balistic vests. This is a solid suggestion with great visuals. Cheers.
