The hanging meat bag is ment to fit inside a pack and hang or just mounted to frame without pack bag. It will NOT fit in T3 pack bag. Have to use your frame as a hauler. A kifaru meat bag just fits in a T3 but it fits very nicely. A good thing to do with a T3 is to put meat in bag and carry a pod to put your gear in the pod and attach outside bag.
They are coming from kifaru with k hooks on top, not 3 bar sliders. The K hooks fit nicely into the webbing that the common loops are attached to at the top of the pack, where the chamber pocket hangs. The finished design is a little different than what's posted in Aron's first video he did covering the new meat bag. I received mine this week and really like the design, can't wait to try it out in the woods.
