Fjallraven Kanken Sky blue- is it real??

I bought this a month ago on Amazon prime and I’m Super conflicted on the authenticity of this backpack. Everything seems to check out however the inside tag that says material says “100% Vinylal” instead of Vinylon F. Does anyone one know if Kanken changed their process? I know the older productions of backpacks did not have a flag logo stitched inside. Another thing I noticed is the some of the flaring on the stitching, is that normal for wear and tear?
