Flak jacket

The flak jacket is a piece of protective apparel. It provides protection to the torso and arms at the cost of a -0.12 c/s penalty to movement speed.

Acquisition

Flak jackets can be crafted at a Machining table once the Flak armor research project has been completed. They require 70 Steel, 50 Cloth, 1 Component, 14,000 ticks (3.89 mins) of work, and a Crafting skill of 4.

Flak jackets can also be commonly found on Outlanders, Pirates, Ancients, and Imperial Troopers .

Analysis

With low resource costs, accessible research, and the ability to be worn over flak vests, flak jackets can provide useful protection in the early-mid game.

However, devilstrand dusters are almost strictly superior. They provide slightly more sharp & blunt protection, significantly more heat insulation, and have no movement speed penalty - their only statistical downside being a tiny decrease in cold insulation. Devilstrand has the advantage of being growable, unlike steel. Mid-late game colonies are often able to grow sufficient amounts of it.

Other late-game materials such as Hyperweave and Thrumbofur, offer similar effects. Due to the speed and coverage detriments of flak jackets, even dusters of strong leathers, like rhinoceros leather may be preferable despite offering slightly less protection to the upper body.

Styles

Ideoligions allow the selection of styles which then change the texture of the certain items and buildings when constructed by the colony. These style variants can be crafted if the colony has the selected style, or can be looted from raiders from factions with the requisite style.
