Hide backpack on my character?

[- Zsquad - IT07]

Hi,

Since I have custom skins working on my server, I have the US Delta Force Soldier skin (with the glasses )
But I wanted to know if it is possible to make the backpack invisible.
I know that if I use a Arma 2 skins, the backpack will be invisible.
But I love my character now with the Delta skin and it looks soooo sweet without backpack; you can see the kevlar vest really good that way.

So, my question is, is it possible to stop my backpack from being visible?

which map and mods do you use to have this skin? rmod?

I have the Chernarus map, and I modified my player_login.sqf from my server.pbo to allow all skins and enable rmod client and server side. easy as pie
