Seat
So I'm 1.96m tall, almost 90 kilograms, slightly trained upper body and have therefore decided to XL. I usually wear XL and rarely L. As it is my second part of G and B, I knew that XL will probably fit well here. Also on the arms, which are usually designed for polo shirts rather for 15-year-old girl there was no problems, spanning no more than it should. Long enough wars with me, this is true for most parts in me KO criterion - not here.
All in all I would say that my expectations have been exceeded. I am sure that it will not remain the last part of G and B.
