My son has done a good bit of hunting with me but nothing that required him to have a legit hunting backpack. He has a possibility of getting drawn for a couple hunts this year that he will finally need one. I would like to get something that he can grow into, use for a couple years, and carry more of the load as he gets older. I am looking at the Eberlestock X2 and was wondering if anyone had used it for their kids. He is an athlete and is in great condition. Thanks
