The Mountain Hauler 4000 is the perfect pack for day hunts or overnight stays when you need the ability to carry meat and horns out of the field simultaneously. The pack provides 3700 cubic inches of non-expanded volume for easy hiking with the capability to expand 800 cubic inches when needed. The internal load-hauling shelf and antler straps beg for the workload when it’s time to get your harvest out of the field. The T-6 6061 aluminum frame provides for an adjustable suspension and a strong chassis enabling you to carry loads upwards of 150 lbs.

Just used this bag on a week long mule deer spot and stalk and loved it. Super comfortable and user friendly. Also carried a spotting scope and tripod a couple of days and it handled the extra weight very well. The adjustments allowed me to customize the fit and it made for comfortable hikes. I put the extra small bag on the waist strap as well as my 2200 range finder on the other side for easy access. It also worked very well with my Sitka Bino harnesses. The only thing i need to figure out is a little better way to strap my bow on. Thanks Sitka!!
