I spend a lot of time on the stand hunting whitetails. Most of the time use a pack to carry few items and mostly layers of clothes. Those of you that own the Mystery Ranch Treehouse Pack what are your thoughts on the pack? From the few reviews I've watched on the pack I like some of the options on the pack, but not sure on the capacity of it. I could always strap my outer shell jacket and bibs to the outside of the pack to clear up some room inside the pack. Thanks!
