I just got this shirt today along with the Outer Science shirt. One thing to note is that these shirts are on the small side since these shirts are in JP sizing. Because of that, I recommend to order a size or two larger than your normal size. In this case, I ordered a Large.

When I first took this shirt out of the plastic, the shirt looked kind of small. I thought there was some mistake but I checked the tag and it said it was a Large. So I tried it and fit nicely. The shirt felt somewhat thin to me but I guess it felt that way since it just came out of the plastic and wasn't worn before.
