It's recast TE2 armor. I've also heard it's not formed very well and is thin in many spots. I would go with ATA armor over this, its a little more expensive but you get what you pay for. You can contact ATA by PMing Terrell AKA Supertrooper on here.
That is the old FX armor, if you are looking for something similar to that I would go with AM armor. It is the updated version of the FX armor, very good quality.
