This guide will let you know how to double your armor which is beneficial and keep you alive in Grand Theft Auto Online. You need to follow the guide to get this trick.
First, you must go to inventory to ensure you have no armor.
Then go to Ammunition and purchase super heavy armor, the green vest. This a plan but not a trick, as you are paying. Now max out your heavy armor by purchasing ten vests.
Go to the phone and call Franklin to request a supply stash which will cost more than 5,000$.
Look at the radar; a little backpack of books will pop up.
Go to get a supply stash that will give you extra health, ammo, and armor, and the best of it is refilling super heavy armor.
Now you have bought super heavy armor through the supply stash, making it to 20 vests in total.
Go to Quick and apply to the weapon wheel if you get any damage. It will initially work through super heavy armor and later go to the backup for heavy armor.
