These are the shorts Jon Jones wore in his victory to become the new UFC Light Heavyweight champ in UFC 128 (March 19, 2011). As you may recall, he beat Shogun in a very dominating fashion, winning by TKO/referee stoppage.
The Jon Jones Form Athletics shorts feature a black and red design with the Form logo on the front. There is also his signature on the left front leg and the Jon Bones Jones lettering on the waistband. A cool thing about the shorts is that there is a grey pattern of small Form icons on the upper half of the shorts.
