This is intended to be gym apparel, but could be worn out of the gym.
We've found that some people want just the text "Hardcore Herbivore" on the front (currently on the back)- or at least not the image of us that is currently on the front of the shirt.
Although it the slogan contains the word "Hardcore", we are aiming for more general appeal than gym rats, so maybe soft-pedal the message a bit. We don't want the tank to appeal only to muscular dudes, for example. Older ladies might wear the shirt (some wear our current design)!
Visually interesting text only is one possibility: styles could be old school hardcore gym, 80's fitness, or even vegetables.
Images could include our old image, or of a badass animal herbivore such as a bull or gorilla, possibly lifting weights.
