WTB- Backpack for my 11 yr old son

[C-5 CC]

My son just got out of Cub Scouts and joined Boy Scouts. He is psyched to go camping and backpacking now!! He has made his list of "necessary supplies" for next year, and a backpack is on top of the list. Thought I might see if any of you have a good quality used backpack that your kids might have outgrown. I am kicking myself for not keeping mine from the "old days". I had a great bunch of gear from my Scouting days, but I can't seem to find much of it after 20 years. Lookin for an internal or external frame w/ a decent quality set of shoulder straps and waist strap. PM me w/ what you have and how much you want for it.
Thanks
Brandon
