Source: bought it new
Purchased my Wilderness Experience Klettersack in 1975-1977? in Chico, California, where they had a cottage industry. I took this-below-picture this morning 6-26-2013: 35 plus years later and it is still going.
It is used regularly still, and it has carried books through 9 college campuses over all those years. It was and still is a great product.
It could use new shoulder straps but it still is functional the way it is!
