A Kevlar vest, true, it is only designed to stop low calibre pistol rounds, and then the protection on it degrades somewhat quickly if shot in the same location. It is also very effective against knives.
Ceramic plates or steel plates on the other hand are more designed to stop rifle rounds from a distance. When you stack kevlar and plates together and then reinforce it with steel you can take rifle rounds somewhat effectively.

The only thing though is even the latest high tech stuff is heavy.
Even though the plates will stop the bullet you also need padding to nullify the impact, which adds weight and holds in heat.

) and you still die with a simple 5.45 round ... or by a simple noob with a shotgun at 100 meters (I'm not kidding).
) you should try to draw a line and stick with it, no matter what. The problem with mods like SS and Oblivion is that, in the end, you are god and thus they gameplay and everything else goes to hell...
