Flak vest

Flak vest

A vest with armor plates inserted on the chest and back. While quite effective at deflecting gunshots and stabbing attacks against the chest, it does nothing to protect the limbs.

The flak vest is a type of apparel (armor) that protects well against sharp/piercing attacks (e.g. bullets, stabs, cuts, bites), and offer minor protection against blunt attacks, explosions and the ever-present threat of clubs, maces, and wild animals. They also reduce movement speed by 0.12. The vest protects torso, neck and shoulders. Flak vests can be purchased from traders, manufactured, or stripped from Outlanders and Pirates. Flak vests are typically encountered after the third or fourth raid, depending on difficulty and wealth (this assumes Rough and Crashlanded scenario, so somewhat 'standard' wealth).


Flak vests can be manufactured at a machining table, once Flak Armor has been researched. A flak vest requires Steel 60 steel, Cloth 30 cloth, Component 1 component, and 9,000 ticks (2.5 mins) to be created, assuming baseline global work speed and no enhancements or hindrances to consciousness, sight, or manipulation. They require a Crafting skill of 4.

Flak Vests are also commonly found on Outlanders, Pirates, Ancients and Imperial Troopers Content added by the Royalty DLC.


Flak vests provide good protection at low cost and for a very small decrease in movement. The vest provides significant protection for the torso, neck, heart, lungs, kidneys and liver, all of which are immediately fatal if destroyed, and which constitute all the body parts that do so that are not exclusively covered by helmets. This comes at the cost of offering no protection to the extremities. For this reason, besides rarer deaths by consciousness or blood loss, a flak vest offers more survivability than recon armor, or its variants the locust armor Content added by the Royalty DLC and prestige recon armor Content added by the Royalty DLC. However, the risk to the limbs is still greater.

Additionally, flak vests occupy the middle layer, meaning that overgarments such as duster or flak jacket may be worn over the top, whereas power armor variants occupy both the middle and shell layers so they cannot be worn with the armor. This further improves the torso protection and provides some, but still less protection, to the extremities.

The combination of flak vest and dusters with highly protective materials such as thrumbofur allow the flak vest to compete in torso protection against the marine armor of similar qualities and their low price, smaller movement speed, and low research cost make them attractive alternatives. However at high qualities for torso protection, and at all qualities in terms of limb protection, the marine armor will outperform any combination of flak vest and duster.

  • Version history

    Prior to Beta 19, it used to be called the Armor vest. It was much more expensive and did not protect against heat.
