I have just received my Medium-Large wesuit and it's snug out of the box.
I am 186cm / 6'1"
Light frame, about 75kg
I ordered Medium-Large because I'm told form fitting is the key and in the water, things loosen up a bit. According to the size guide, I'm smack in the middle of the M/L size.
The only issue I have is the neck line puts some pressure on my neck/shoulders/collar bone. Is this too small? I'm concerning a large might be too big. Swinging my arms around, there is a little restriction, but I don't now how much is acceptable, and how much is too much
