I bought an Arcteryx pack which isn't hunter specific but they are the best of the best for comfort and quality but you pay for it ($500-600) If I put a good amount of weight in it and go a good distance 15+ miles Im a hurtin unit at the end.. I couldn't imagine doing that with a cheap pack that doesn't fit me as well as my Arcteryx.
I also know a guy that's selling his arcteryx medium 75 or 65 liter altra if interested
