Kelty Tioga frame backpack vintage collectors' item  early 1970s?   $25
This was about the pinnacle of frame backpack design -- even before they invented sternum straps.  I had one of these once.  I was tempted to cannibalize the hip belt buckle; it's the coolest thing you've ever seen.
They don't make 'em like they used to. This hasn't seen much use.  Found it at a garage sale.
I'm in north Seattle.

That buckle held when it was supposed to, was much quicker to open than the Fastex when having a waist strap was suddenly a bad thing. Could pinch a little.

I carried some massive loads with my tiago.

Still use it for beach clean up or removal of major trash sites back in woods.
