What was Vernon Davis wearing?

I was watching his combine work out and he was wearing some kind of compression shirt with a weird design I have never seen before does anybody know who makes it.

It doesn't matter. We have a better chance of drafting Barry Sanders.

he can still wonder what his shirt was...

i thought it was just taped up.

no,it wasnt tape.a couple of the other guys were wearing them also.almost looked like it was part rubber around the shoulders

maybe it was like underarmor... just something to keep them dry instead of running around swimming in their own sweat (soaked t shirts).
