So I've bought several lots of armor for my characters but it keeps disappearing when i go back to them. Is it being used up when i get shot or am i being totally stupid?
@morningstar: but do I need to keep on buying new ones? Or can I equip the ones I already have.
If you don't see a light blue colour on your body armour bar then it means you don't have any equipped on your character and you'll need to buy new ones from Ammu-Nation.
You can't "equip" body armor. Just think of it as extra health, you either have it or you don't. There is five sets of body armor at Ammu-nation, each one filling your bar a little more than the previous. You don't keep some in stock, the blue bar is what you have.
