I think it's the standard ram tri-fold soft tonneau cover. That's what the photos on the website show and what my co-workers new 2021 limited night crew has for a cover. I was unaware of another option. Do you want to see a photo of my 2020 OEM tri fold cover open? Mine is a 5'7". I love it, the latches are very well made, it's also self centering if removed and it has a great profile above the bed. I know its 2-3 times more in cost than soft aftermarket ones, but I have to say, it's worth it. The vinyl stays very tight as well.
My only issue is it's wider than the 5'7" bed is long when removed. So, with the tailgate up, it does not fit in the bed unless it sits at an angle, or it hangs out when straight with the tailgate open and it does not fit across the cab to store in the back seat.
