What is the College Football Team that has a "mountain goat" mascot and begins with N*?

I just got an awesome jacket from someone, but I don't know what team it is. All know is that it is a College Football Team in the USA, and the colours are: black, yellow, with white stripes. My friend who gave the jacket to me said that there was also a jacket from the same team that had navy blue, yellow, and white stripes. Help?
