Really happy with this jersey, It's not as tight as I thought it might be, maybe US sizing differs slightly to the european purchased Giordana gear that I own. this isn't a bad thing.
I'm a tall rider with a muscular build and this does not look short on me or problems with the sleeves been to tight.
The fabric is extremly soft and stretchy so you get a good fit when sat in the saddle.
Just hope that the material holds up over several washes. I have found Giordana to be of good quality in the past so I have faith.
For sizing i am 3XL but i am stretching the sizing boundaries by being 6ft 7" and 95kg.
Overall very pleased.
