The Attack Pack Pro is a perfect example of progression with design. It's light, flexible, vented and comfortable. Moreover it compresses in size with each pod you remove. Resulting in a perfect combination of versatility and compact size. The Attack Pack Pro can hold a range of pods, from 4 all the way up to 11. Depending on how many you use, the harness conforms to what is needed. Continuously self-adjusting to help maintain the lowest profile. The belt system is now made of woven vented-fiber memory elastic. They retract neatly into the harness, again helping to maintain the lowest profile possible. The complete list of features is quite extensive. We couldnt help it. We had to describe the most important highlights we thought you'd want to know.
