The "middle child" of the lineup, the MRK 4 splits the difference between large and small meat haulers. Coming in around 4,000 cubic inches of storage, the MRK 4 features a top-loading design and our highly effective "split-pack" design which allows the pack to drop away from the suspension and carry your meat closer to your body. The result is a more comfortable heavy haul and a less exhausted hunter. That means more time and energy fora |hunting, of course.
