I thought the mask was the same one he wore last season, but then I thought I noticed a difference on the chin. This season he had his number, whereas the previous season I believe was his nickname.
This was the 2015-16 mask (notice the chin difference.) Other than that the design looks very similar.
The photos below are from the 2016-17 season again.
