Kelty backpack. I think he purchased it when he and my brother backpacked The Absaroka Range in Montana in 1982. He told me when he purchased this pack, it was the largest pack they sold. My father brought two of everything into the woods and he had a large frame as well, so carrying this large pack was no chore to him.
In the end this is a 30 year old pack that has been from Texas to Wyoming and all places in between. Now there are newer and fancier packs, but when I wear this pack it just takes me back to when I was on the trails with my dad.
