I have two T's ( a v-neck and round neck), 3 case badges, and a Techimo bag
Mine fit great LOL
Now I'm waiting for TechIMO caps - the better to keep my hair do done when flying about in my *I don't fear being decapitated by an 18-wheeler* convertible
Mine "fits" great too, and I now have 3 more on order
If you're wondering about the sizes, I'd say they're exactly what you'd expect for a T-shirt. I got a large, which was just a little too big until I washed it (100% cotton)... now it fits perfectly. ;D
