Metallic blue Sypder Sonix with 14 ounce co2 and 12 ounce backup.
Mine is the identical product by Viewloader, so the good is that it doesn't say Ass Eagle on the flap. Also, it's got some seriously tough belt loops on the back. And you can thread a belt through one loop, then a loop on your pants, and then through the other. That way it won't slide around.
The belt it comes with is garbage. Use a real belt to keep it from loosening and ending up around your knees. Also, when you use half a can, the other half that you put back in the harness will break and that half can you thought you had will be useless. But that happens with any harness you put a half-full can back into.
Good price, good availability, not too cumbersome. Nice for players who won't need that many balls. ie snipers, players in small games who won't be shooting 2000 balls a game, etc. I play with a small group of guys (between 11 and 17 besides me) at an abandoned public facility and I only carry 400 balls with me and that usually lasts me just fine. I can live on 400 balls for about 2 hours because of how spaced out the field is. Its seriously like 10 square acres with 18 guys spread out in there. Verdict is...its a good harness, buy it.
