I've had one of their packs for a good 15 years, I think it's the lost river.
I love this pack and I use it every season. Zero problems and well made. Very quiet with the wool and extremely comfortable. Pricy but good investment. Ie: 15 years and I'm sure it will last that many more.
I pretty much use it as a day pack. I tend to take extra gear in case I have to spend the night out or have an emergency so I have all the typical survival gear.
Living in a rain forest I always have to have rain gear, etc which attaches well with no movement. The design of the pack allows you to shoot your bow with no problems.
Enclosed waterproof sack works if you quarter your deer. I had the hip belt modified. One side has the small pocket, the other side has no pocket but instead it has two lengths of strong belt material with snaps. It allows you to carry items on your hip. On mine I usually carry a large hunting knife, bear spray (big bear area where I live) and a GPS in it's belt case. They all fit fine and are nice and snug.
If ordering again I would for sure modify the belt, otherwise you can't carry all the things I mentioned.
I'm sure there are other great packs but you can't go wrong with this one, for sure.
