I have an Outfitter pack. Awesome pack. Wish I would've gotten it years ago.
I do find it too big for everyday treestand hunting though. I'm probably going to go to a Haversack for that. But, I don't usually carry too much for everyday treestand hunting.
On the other hand, the Outfitter is about perfect for a full day for roaming away from base camp. Can fit extra clothes/rain gear, water bottle, food, first aid kit, etc. etc.
Highly recommend their products. May be looking at a larger pack for short hunts in the backcountry.
