If they are that poorly made, then return them and badmouth them online. They should not continue to sell crap.Return it and inform them if there's any problem or handling charges you will start bad mouthing their fins jerseys online wherever those products get rated by users (with accompanying incriminating photos of how bogus they are).
I'll buy my Tannehill jersey and Dolphin gear once they change the logo & jersey. I remember how much it sucked buying all kinds of gear when they changed the logo the last time. I'll hold out til next offseason to stock up.
