I'm nursing a tight hamstring and I'm heading out for a tournament down in Memphis this weekend. I don't expect the weather to be really cold but my hamstring gets tight with the cold. I'm finnaly considering buying some Under Armour undershorts to keep it tight and warm. Under Armour offers two versions of their undershorts a 7" and a 9". I tried them both and I prefer the longer version since it goes almost to my knee where my injury is. The thing is that the 9" shows quit a bit when I'm wearing my OSI shorts . I've heard some referee uniform Nazis saying that I shouldn't even wear my mock neck black undershirt as it shows when I'm wearing the pro style shirts. This is the first time I'm attending this tournament and from what I heard it is a good level tournament and I want to look nice. I'd hate to be judged by the fact that about 1 1/2 " of my undershorts is showing under my shorts. What do you guys think?
