The McCoy Jacket and the Wasteland Vests both have pockets for back armor. The McCoy comes with all the armor included, but the Wasteland Vest does not include the armor. It has to be bought separately.
An advanced, patented polymer, CE-rated D3O® impact protectors are the latest advancement in protective armor. D3O® impact protectors utilize intelligent molecules that lock together on impact. Because of this, the impact protector can be made thinner and lighter, making a jacket more comfortable and easier to wear. However, this decreased size does not come at the expense of impact protection.
