|As a Weapon|
This is a light clothing item made of cotton which covers 95% of your torso and arms, and which has a bit of storage capacity. It is somewhat bulky, encumbers you a bit, and will provide some warmth to the areas it covers.
It offers very low protection against bashing attacks and very low protection against cutting ones (that includes bullets), while offering no protection from environmental hazards .
It can be made to fit the character's body via tailoring or mechanics, will increase warmth for your hands if they are cold and you aren't wielding anything.
