The club have sent out a useful kit guide with the physical shirt measurements.Normal XL is 58cm across the chest going up and down in 3cm increments.Pro XL is 53cm across the chest going up and down in 2cm increments. Fits appear regular as waists are about the same size (1cm smaller) as the chests.
From my experience the Kappa shirts are all on the small side, so if you're between a L and XL I'd definitely go for the latter. I've got a L in the normal away shirt, and an XL in the pro home and third kits.
I'm wanting to buy this season's home shirt, and I wondered if anyone had any experience with what the fit of the 'stadium shirt' is like compared to the 'pro shirt'?Basically, I'm keen to hear if I should get a stadium shirt in my regular size or if it's still a little tighter compared to 'normal' clothes? I'm somewhere between an L and an XL so keen to get it right.
