The primary difference between the new Jordan uniforms and the previous uniforms is the new ‘SOONERS’ and ‘OKLAHOMA’ text, a change that comes with OU’s updated font. Also, the helmet decal on the traditional helmet is a bit thicker. The Jumpman logo replaces the Nike swoosh on all four uniforms.
The Rough Riders uniforms no longer have the armpit spikes. The leg stripes on the Rough Riders now align a bit more with those seen on the traditional uniforms.
