My back problems mean I can't attend this weekends UK NFL game between the Pats and the Rams so I've sold my 2 tickets to my friend...My wife told me I can use the money to treat myself to a Texans Jersey to cheer me up. Here's the thing...I've got my eye on a couple of Authentic jerseys online but I have a size query you may be able to help with. I'm going for the authentic over the nike as the quality of authentic reebok will be better and the price is quite decent. I'm sure plenty of you own an authentic reebok jersey . Whenever I've worn the normal 'replica' screen printed jerseys I've always worn a Medium ..usually the measurement is around 23 and half inches armpit to pit. This size fits quite well. Now the Authentic reebok I have my eye on is a '46' . Does anyone know if this means the size will be 23 inches armpit to pit? I ask because the screen printed replicas can vary between size of jersey and actually chest size (eg, a M 48 Jersey might be a 46 chest size and so on). With the authentic I want to gauge the size before I buy. So would a size 48 be 24 inches pit to pit, a size 46 - 23 pit to pit..etc etc? Thanks in advance.
