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 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.


Flak vests can be crafted at a Machining table once the Flak armor research project has been completed. They require Steel 60 Steel, Cloth 30 Cloth, Component 1 Component, 9,000 ticks (2.5 mins) of work, and a Crafting skill of 4.

They can also be bought from orbital, Outlander, or Empire Content added by the Royalty DLC traders, as well as Outlander and Empire faction bases. Flak Vests are also commonly found on Outlanders, Pirates, Ancients and Imperial Troopers Content added by the Royalty DLC.


They also reduce the wearer's base move speed by 0.12 c/s. The vest protects torso, neck and shoulders.


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 (if one of them is already destroyed) 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 low 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.

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 outer layers so they cannot be worn with the duster. The duster further improves the torso protection and provides some, but still less protection, to the extremities.

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