The Ultra400 version of the Big Wild. This pack is made with the lightest most durable fabric we could find. If you're looking for the most capable, light and durable load hauler around then you have come to the right place. The main body is made out of super tough Ultra400 which has a 400D UHMWPE face fabric and is laminated to a .5 mil poly backing to make it waterproof. The bottom and stress points are made out of bombproof Ultra800. 


Named after our hometown stomping grounds which is often referred to as Michigan’s Big Wild. This load hauling pack is perfectly at home in any of the big wilds you may find yourself in. Whether floating the south fork of the Flathead, or on an extended trip in the Brooks Range, this pack is ready for any of your adventures.


The combination of the frame, suspension and contoured body shape of this pack make it a very capable UL load hauler. The twin stays are made of 7075 aircraft grade aluminum which will not deform under heavy loads. The stays are directly connected to the load lifters up top, and the belt down below making for great load transfer to the hips. The full wrap hip belt on this pack is incredibly supportive and does a great job of transferring as much weight as you would like to your hips. The suspension is overall very light, effective and simple.
