I was on a trip recently and saw a lot of pilots with the same roll aboard. It had a metal frame along the edges on the back with a metal handle that was wrapped with a round cover. I didn't get close enough to see what brand they were or have time to talk with one of the pilots or fa's that was using it. It looked nice and rugged. I could tell they had all been used for a while by all the little scratches in the blank paint on the metal on the edges. Anyone know?
