The vest itself is in the style in the South African Defense Fore M83 vest. As you can see by the watermark this one is made by Mil-Tec, so its never going to be operational quality but likely to be a similar level of viper, maybe slight better.
As for the vest I had one years ago and they're quite comfortable with an alright design etc. If you're just starting out on a tight budget I'm sure it'll do fine, but you'll probably want to upgrade fairly quickly
