All Grid Armor versions look the same. There are a number of different visual bugs with Grid Armor that can make it look like hair is sticking out of it, or that it is equipped with an additional armour piece.
Here's one of the visual bugs. By smurfing off all armour, smurfing on a Yalmaha, smurfing on Grid Armor, smurfing the GA off again, then desmurfing the Yalmaha, Papa Smurf here looked like he was wearing the GA even though he was not. He could then smurf on Omni-Med Suit Boots and Trousers and a Santa Hat to complete the Smurfy look. (Gargamel beware!)
