This is George. We bought the Armour that you are speaking about through Bill Kipp (Fast Defense). It is called Predator Armour. The link to the website is https://www.predatorarmour.com/
If you have questions you can ask me. I use this Armour with my students.
The suit is awesome for impact. You can take a baseball bat to this thing with full power and the suit protects. I have trained with many different protective suits and although this one looks funny, it is by far the most effective. As for buying one used, I can keep an eye out for you and let you know.
