Here are some of my proposals. Instead of creating a separate icon / typography combination, I've created an all encompassing logo / unit. One that can be used for additional elements just as branding stamps, watermarks, shirt badges/embroidery etc.
The logos are 100% vector so will scale well to any size, and works well in full colour, B&W and on coloured backgrounds if needed,
It would be my pleasure to work up any variations so please do say. I look forward to your comments or thoughts.
Entry 4 is a good direction, particuarily with the green version, however the colors are conflicting. Perhaps the outer ring in the green design could move from white to the same green and the outer text white? This might also help keep it safe from being a touch busy.
