As for OP, my weekend team uses Kobe jerseys. I like them too, as they fit nicely around the neck and the sleeves also don't feel to loose. Fit around the torso feels balanced. Not super tight but not too much fabric, either. I like it.
My jersey size is Adult Goalie. Not sure exactly what size, but I'd guess Adult Goalie Large, as I'm a small goalie (5 FT 5) and it works for me.
If you're a bigger guy, maybe you should go for the Adult Goalie XL jersey size ?
Let me know if you need a picture and I'll see if I can grab one to show the cut.
