Just picked up a Feildline from Wally for $20. Looks heavy duty enough. Its a three day pack. Has plenty of room, very comfy. One thing I like about it is the 2 steel leafs that ride on your back for support, the waist and kidney strap for comfort. Suprised by the large capacity of it. I hunt in some frigid climates at times and pack in quite a ways so thats important to me. That way I can carry my warm clothes in to where ever I'm going. Also shed hunting in the spring it will come in nice for carrying antlers.Have yet to see a pack this nice for $20 bucks. Other good options are those military surplus packs on ebay. If I wouldn't have found this one I would have went that route.
