the polos are very nice, the blue and gold strip under the arm up and over the shoulder has some stretch to it, very nice. Only problem i have is a i ordered a medium and been out of training for a few weeks so need a large as it's thigt round the shoulders. Be right after Xmas when i get back into training again.
I have a M in the Black training shirt and a L in the blue one and there is not much difference in the sizes of those two maybe a bit bigger in the arms the L is compared to the M. But really good gear the Blades stuff. 10/10.
