The Attack Pack Pro was specifically engineered to work with a range of pods. With the variety of today's games, from X-Ball to 5 man, 7 man, and even 10 man, the amount of pods needed is ever-changing. Why have 4 different harnesses when you really only need one? The Attack Pack Pro can carry up to 11 pods, and eliminates large, excessive harnesses by compressing with each pod removed. This compression allows you to maintain the lowest profile possible, and helps to keep you in the game longer.
