Built around Eberlestock’s innovative Intex II™ aluminum frame, the Warhammer™ is a great load-bearing, 3-day pack. The two large butterfly compartments helps you organize your gear and increase storage capacity by rotating them outward. The Warhammer can be adapted for more capacity by zipping in a Super Spike Duffel™, or built into a higher capacity version of our Skycrane II™ by adding a Little Brother™ and MultiLid™.
