The Kevlar vest and helmet, known in Counter-Strike: Global Offensive as simply "Kevlar + Helmet", is a combination of protective equipment found in the Counter-Strike series. Kevlar can be purchased by itself, while the helmet cannot. 

Overview

Kevlar body armor costs $650 and reduces damage taken by players from bullets and grenades by a percentage that varies with the armor penetration of each weapon. Each time the armor is hit, the armor value will drop by a percentage based on how much damage was absorbed. Armor disappears after its value reaches 0. A vest will reduce damage and remove aimpunch from attacks to the chest, stomach, and arm hitboxes.

Aside from reducing damage from weapons, Kevlar can also reduce environmental damage such as fire, toxic materials, etc by 50% in some custom maps.

Players can also buy a vest with a helmet for $1000, or add a helmet to existing armor for $350 as long as the armor value is still 100, which extends protection to the player's head. The helmet can save players from headshots by most weapons with the notable exceptions of sniper rifles, the Desert Eagle, the SG 553, and the AK-47. Like the vest, the helmet removes aimpunch from headshots.

As long as the armor value is not zero, the exact armor value does not matter and damage will always be reduced. Therefore, having higher armor value does not give better protection unless the value is reduced to zero.

See tables below for armor penetration values of each weapon.

Grenades / Melee Weapon Armor Penetration Grenade strike* 50% HE grenade 60% Incendiary grenade 73.75% Knife 85% Molotov cocktail 90% * all grenades deal 1-4 damage on direct hit depending on range/hitbox, this is halved by armor and may do 0 health damage.

Explanation

As long as the armor count is not 0, damage will always be reduced. The formula for damage to an armored player is as follows:

Damage to an armoured player = damage to an unarmored player multiplied by the penetration power listed above.

Rebuying Armor

In general, the point at which rebuying armor may become useful is found by determining the maximum damage to armor that may be sustained in a round before the next damage applied will kill the player. For example: of the most commonly used weapons, the weapons with the lowest Armor Penetration (and therefore lowest HP Damage to Armor Damage ratio) are the Glock and P2000. The Glock can inflict 12 HP damage/8 Armor damage. A player can therefore survive up to 8 hits before dying. The maximum value of useful armor in this instance is 8*8=64. Contrast this with the P2000 which can inflict 15 HP damage/8 Armor damage. At this rate, a player can survive up to 6 hits before dying. The maximum value of useful armor in this instance is 6*8=48

Unless a team can afford full buys for the rest of the half regardless of round wins/losses, it is important to consider the point at which rebuying armor is equitable and not just the maximum armor potentially required. Another example is as follows: of the most commonly bought weapons, the weapon with the lowest Armor Penetration is the M4. The M4 typically inflicts 22 HP damage/5 Armor damage. At this rate, a player can survive up to 4 hits before dying so the maximum value of useful armor against this weapon is 5*4=20

If a player previously bought a helmet + kevlar, is shot, and purchases the helmet + kevlar again in the next round, the player will only be charged $650 to replenish the damaged armor, regardless of where the player was shot.

Trivia

• The hotkey for this equipment is b51/b52 or o1/o2.
• Kevlar vest protects the chest, stomach and the arms (starting at BETA 1.2) while the helmet only protects the head.
• In Counter-Strike 1.6, if a player is shot in the head and the shot causes the armor to reduce to 0%, the normal headshot sound is heard but the helmet impact can be seen.
  • If a player is shot in the head while wearing a helmet and assuming the shot is non-lethal, the third person view will display the player's head snapping violently back and forth. This however, does not appear in Counter-Strike: Source as players will never flinch when injured.
• Kevlar armor in Counter-Strike: Condition Zero Deleted Scenes provides significantly better protection than its multiplayer counterpart, and can be found in the environment in most missions. However, no helmets are obtainable in Deleted Scenes.
• There is no visual difference when having armor and helmet equipped.
• The world model file for Kevlar is named "w_kevlar" while the Kevlar and helmet is named "w_assault".
  • Kevlar and Helmet is referred as "assaultsuit" in the game files while the Kevlar is still "kevlar".
  • On the Dynamic Weapon Pricing website, the Kevlar + Helmet combination was known as the "assault suit". 
• If a mapper has decided to use content from Half-Life and place the battery used specifically for the H.E.V. suit, players will gain 15 points of armor. In some custom servers, if a Half-Life NPC is used, the Kevlar has the same properties as the H.E.V. suit. This mechanic also applies to medkits (which heals the player instead).
  • Moreover, both the H.E.V. and health recharge port is usable in the GoldSrc Counter-Strike games.
• Although the world model of the Kevlar does not appear in official maps (except the training mission from Counter-Strike 1.0), some custom maps feature the MDL file that can be obtained by players.
  • Note that when a player's Kevlar is reduced to zero, he cannot pick up a new Kevlar vest by walking over it.
• It is impossible to purchase or obtain the helmet discretely.
• The Kevlar and Helmet is less effective in Source and Global Offensive as armor penetration from most weapons is increased.
• The SG553 in Global Offensive is the only weapon to have 100% armor penetration, thus the armor value never decreases whenever the player gets shot with it.
• The VIP in Assassination scenario has 200 armor, which will reduce damage by taking the initial absorption as explained above and then reduce it by 50%. However, since he is the top priority, he must rely on his teammates to ensure his escape as his unique armor count is not a substitute for adequate protection.
