Our Zulu has been so popular that we've designed the Zulu Extreme Ruck for those who need even more capacity. We've created a ruck that is more than just a "bigger" Zulu - we've kept some of the favorite features such as slot pockets, over the top compression straps and extendible top lid. By combining features from the Zulu, Pointman and EMR, and adding even more new features, we feel the ZXR is in a class of its own when it comes to combat rucks.
