My cheap no-name Chinese backpack is finally falling apart, after over 20 years of absolutely solid service.

I want something that will last at least another 20 years, will hold a modern 16" laptop (e.g. Macbook), and will also let me toss a pair of jeans and light jacket in, when I ride home from work in the spring and fall afternoons.

I'd like to avoid American brands if possible.

Looked online at the SwissGear 5698 and Endure, but don't know how well they're built, or if they'll hold my junk.

Any recommendations?
