Mystery Ranch is still doing pretty well for themselves. (I'm amused knowing that they crank out harnesses for Amazon employees left and right for their robot safety systems.)

I'm also a Red Oxx guy. Love my Sky Train backpack when I'm flying out. They quote a "no bull" warranty, and their CEO suggests to "be sure to include them in your will."
