I have an S bag, bought in 2013. It is fine, but the strap is something I never use so decided to take it off. You can't. It is sewed in one side, so either you cut, or you waste a side pocket by rolling up the strap and putting it inside.
That's one thing. The other is potentially more serious: the plastic fitting that clips the frame to the mount is riveted with 4 rivets. Mine only has 3, since one has broken off, with a second beginning to work its way out. Given this is a high use stress point, I'm not convinced that sufficient quality rivets were used, or the QC was especially good. Given this bag is not inexpensive, I am a little disappointed. I have repaired the mount, but, even so, it's the only bag I've ever had to do so.
Anyway, I believe they've changed the design, which is kind of admitting there were flaws in the first place.
