Thank you both for the great responses!

I went to the local Samsonite Outlet and asked about the F'lite. It seems they have replaced those with the s'cure series. But they seemed quite well designed, with structural segments inside the bag sides to add rigidity while cutting down on material and weight. The seal was still there and the latches seemed decently good. Was a bit on the pricey side even with their 20% sale so I passed. But if I come across this bag or an f'lite on a good enough sale, I'm sold.

I've found some original Oysters online, but they're too far away. Why can't the good stuff just kept being made good?
