Narrative:

At approximately xa:15Z the pilot flying noticed we were about 500 feet above our assigned block altitude FLX50-X70 and climbing at 200 FPM. This was brought to my attention; pilot flying quickly corrected the error; and we resumed cruise flight at FLX70. No other aircraft were around us and nothing was said to us by the center controller. Flight continued uneventfully.ultimately both the pilot flying and I were distracted and tired. Both of us had reported in a tiredness the night before after several long tough days. Neither one of us got the amount of quality of sleep we wanted for that day. In addition; we were in an in depth discussion on current events and I believe that added to the distraction. We were in the block FLX50-FLX70 but level at FLX60 when the pilot flying communicated and decided to climb to FLX70. I acknowledged that; but failed to realize that the altitude selector was never reset from FLX60 to FLX70. Under normal circumstances I would have trapped that error; but I believe the aforementioned factors contributed to me missing this detail.this was a breakdown of SOP. Both of us are to blame for letting our guard down and not remaining diligent despite the fact that we had now flown together enough to trust each other. Sometimes it creates more errors when you trust the other person too much; it makes it easier to deviate from SOP. I believe this error was caused by a multitude of factors which have been mentioned above and to prevent that in the future requires more diligence on my part and the part of the pilot flying.
