I'll be going out for multiple days in backcountry, and I need a pack that has the capacity for gear and that's expandable to pack out meat, but that also fits my torso length. I bought a pack last year that was too long and thought it would be fine. It wasn't. I've looked at stone glacier packs because they seem to be the most adjustable, but i'm not willing to pay that kind of money unless it is a perfect fit. (and even then...sheesh! expensive!) I saw the Monarch backpack by alps outdoorz, but it's just a day pack and doesn't fit the bill. Any recommendations?
