This mod is the Mohawk Helmet mod, what it adds is pretty much explained by the title.
This mod comes in 4 different colours red, green, blue and black!

Thanks to icebox84 for suggesting this!

NOTE: This is designed for the helmet and may look a bit weird when not wearing the helmet.

DISCLAIMERS

I did not create the MaskAlwaysOn.cs!

Installation:

Using OpenIV, replace "prop_welding_mask_01.ydr" of your choice by going to:
x64c.rpf\levels\gta5\props\lev_des\v_minigame.rpf\
and importing my model.

NOTE: YOU NEED TO HAVE SCRIPTHOOKV.NET INSTALLED (If you don't have that, get it here: https://www.gta5-hub.com/tools/scripthookv-net)

Then drag the "maskalwayson.cs" into your "Grand Theft Auto V/Scripts" folder.

How to use:

Just equip a helmet then simply press 7 on the numpad!
