UNDFTD Sizing Question

I'm wondering how the UNDFTD Corporate Crewnecks fit ? I'm not sure if I should size up or stay TTS (I'm a Size Large in T's) because I've never bought fleece from UNDFTD, just T's. I like my crewnecks to fit a little bit more on the baggy side too. Any help is appreciated, thanks blushing
