I see everyone mentioning that kiver will protect your head from some types of rounds, which is only half true. First off, kiver is only level 2 armor. It will block non ap-pistol threats, but even rifles loaded with the worst ammo will go through them like butter. As for how scavs with grachs kill people in one hit, they all spawn with the +p pst ammo. It will go through that level 2 armor every time. Secondly, kiver covers the head. Doesn't do a thing for the unprotected face. I can't tell you the amount of times I've shot a geared guy in the face with a handgun on stream, only for him to drop like a rock. The armor will protect you from makarovs, shotguns, melee weapons, tokarevs. They won't protect you from shots to the legs, which only require 2 shotgun blasts to kill, or shots to the face. Shot placement is very important.
