Was wondering about any pros or cons about this pack system. Thanks! Any military inputs...

I use an alice frame with Molle straps and waist belt. Pretty comfortable but pretty heavy before you put anything in the pack.

I tried the same straps and belt on my tree stand, it added at least 5 pounds to the stand. They sold the combo with extra long straps to attach to a treestand on fleabay.

ttt for some more input,
Thanks
