My 12 yr weighs about 100 lbs and is a bit of a little ox in terms of strength, but is short so most packs run large for him. He does have a decent youth hiking pack with an internal frame, but it is as noisy as all get out... Any well built youth hunting packs out there that are durable and built for a youngster? I don't, of course, want to put out a huge amount for something he'll outgrow in a season.
