If you plan on hauling gear in using the load shelf, I recommend you watch this video:
Accessing the load shelf is very easy, but there’s velcro. Not the end of the world, probably make way more noise climbing, but it’s something I don’t prefer.
I do think the K4 frame is really smartly designed for comfortable carrying, but I personally favor layout features of some other frame pack options for my saddle hunting setups.
I’d just suggest considering if the K4 is fully compatible with your hunting setup. It’s unfortunately not ideal for mine and it kind of bums me out.
