This post was inspired by a thread on SportsLogos.net.
In 1996, the San Francisco 49ers introduced a new uniform set partially inspired by their 1994 throwbacks. These new uniform featured a new logo, drop shadows and white pants.
One of the major changes was the addition of black to the helmet stripe. The 49ers removed the red-white-red helmet stripe and introduced a black-red-black stripe pattern to match the new white pants.
