I want to buy the track jacket from 2012 Olympic games http://www.kitbag.com/stores/kitbag/products/product_details.aspx?pid=94871 I wear size Men's large in t-shirts, which is about 42-44, so is a XL 44-46 going to be HUGE or fit just right considering I will wear tshirts and long sleeve shirts underneath. Does anybody own it? How does it fit? What kind of jacket is this? Is it a windbreaker or track jacket http://www.kitbag.com/stores/kitbag/products/product_details.aspx?pid=94880 I need an answer ASAP they are running out of sizes
