Muay Thai Gym T-shirt Design Project

C'est ce que bulldogbalmain recherchait dans leur t-shirt design

HI, I run a muay thai gym in sydney australia. I am looking for some different design tshirts to sell in my gym. The gym is called Bulldog (location of it is Balmain) 1 idea I would like is a Team Bulldog tshirt.
It doesn't have to have my logo in it. I am open to 1 colour or a couple of colours with in the shirt.
I would like the front and back with something on it. smaller on the front and larger on the back.
lets see what you come up with
Thanks
I have attached another image of a shirt I have had before. It has another persons logo on it.
But I like the F R F up top. Maybe I could have B M T in a font like the one he has or similar Voir plus
