Utmost quality and perfectly designed for the K4 pack from Exo Mtn Gear. Attaches/detached easily and adds the ability to haul meat or sandbags w/o your main pack attached to the frame.

This thing is great! Only used for conditioning so far, but makes it easy to load weight for training.

Great backpack and Service
I purchased the K4 3600 Pack System at the Hunt Expo in SLC with a couple accessories. I ordered a few more accessories online after the Expo, which they honored the same Expo promotions. Lots of adjustments and customizations to fit me perfectly and comfortable for the heavy pack outs.
