Battleship... more like Cloud Surfer. The adjustable shoulders & hips are the make it or break it of these types of packs. This system in particular made 50lbs of gear feel like 15 once I had everything adjusted & fitted correctly. I was damn near speed walking compared to the rest of my team & it was all thanks to this pack. I have tried many different brands & styles of rucks & I have to say, I am more than impressed. Suddenly, my whole team has been outfitted with Eberle rucks haha
