I just wanted to let you all know that we received the Jake t-shirts and they are indeed very soft and seem to be of good quality, but please have in mind that they are quite small! I usually use Medium size for most brands (Inditex brands, Nike, Qwertee T-shirts, Fangamer T-shirts, and so on). (I'm 1,83/70kg, on the slimmer side). The Medium size for this one is quite tight (specially the short sleeve are like very tight to the arms) and a little bit short. I already washed them before trying because I was sure that they would be OK, so I was really surprised when I tried them and now I won't be able to change them, so I'll have to gift it to someone else and order a Large one next time
So, basically, I would consider going with a bigger size if you don't want the t-shirt to be really tight.
I guess this applies to all sizes...
