I like a frame in Minnesota. If I’m carrying 8-12 lbs of climbing gear, deer down kit, range finder, trauma kit (I don’t go in the woods without a tourniquet, Sam splint, chest seals, decompression needle, and trauma dressing), and then several large bulky layers, it’s much more manageable with a frame pack.
I’m going to start this season with the Catquiver VII I bought this year, since I’ll be one sticking this year. But I bought an Eberlestock Renegade for $125, the X2 worked great last year hauling sticks, platform, and late season below freezing gear.
Any time I see someone say they walk in hunting without a backpack, with just stuff in their pockets, I can tell they don’t walk far or don’t live near the Canadian boarder.
