We decided not to make any changes to the shirt, since everyone has different things he'd like to change, so we can't please everyone. What we can do is produce shirts without anything on the back? Let us know if you'd buy one like that at Amsterdam or Prague, and which size. Thanks!
I buy a L or XL(if you make that)
I will give Graeson the Euros, he pick it up 4 me

No, we don't make XL, but L is pretty big! I'm 186cm and I prefer size M. But also I prefer the shirts being more tight.
As you said, if someone isn't going to Amsterdam or Prague, you can ask someone who you know will go there and lives near you, so they can send it to you and shipping cost won't be that expensive.
