98% of the time we get on the truck, the only other people we see is fellow CFS members, at staging area, meal time or on the fire ground. I think as long as you brigade wear the same it works, you don't look like dad's army.
Yes have the star(because it stand for something)and logo if you want, as said there is no missing our trucks.
We went blue with yellow because its off the shelf, 100% cotton and low cost.
As this discussion shows by the time we decide what the majority want(others will want different), get the CFS to give it the tick, then to actually get them. Our current shirts will be dress up cloths for kids or rags and the next lot will be worn out.
P.S. I have seen some brigades at meal breaks all wearing the same shirts, their crews do stand out.
