here is a good pic for on the back of the shirt

my 2 cents , keep what you print on the shirt from being to covering , leave some space not one solid picture , too often the shirts that have a lot or large picture get stiff and don't breath where the picture is. when it gets hot you don't want to peel that off yourself.

I will give you the idea I have had for several years. Call them "One More Step". That logo on each shirt with a variety of animals approaching different sets. Such as coyote at a post set, fox at a dirthole, coon at a pocket set,etc. You can have numerous shirts appealing to all types of trappers. Just cut me in.
