I made a simple re-texture to make the gunner flannel shirt and jeans look newer instead of having patches of cloth sewn on all over the place.
I also removed the shiny studs on the boots.

The normal maps and specular maps used are the same as the regular flannel shirt and jeans, so having modified those, your regular flannel shirt and jeans will look off, unless you use the regular flannel shirt re-texture as well.
