More from the "Somewhat Subtle Sonic" selections at the Sega Shop. These are the "Bootcamp Sonic Special Operations Unit Long Sleeve T-Shirts". They're adults sizes only, and about 30 dollars each. They're a simple variant of each other, either black with tan logo, or gray with blue logo.
The logo is small on the upper chest area, off to one side. It is the 'military patch looking' small Sonic face in an oval with some stripes.

There isn't anything particularly 'special operation' about the small logo from the Forces game, but it's an ok tee if you needed something that's winter-ready but also pretty plain.
