The EarthPrix™/FormulaEvo™ T-shirt is in production and will be available soon.  We’ll post the details - price, how to order, etc. - when we have it all figured out.  For the time being, they will only be available in one color - charcoal grey -  and sizes S-M-L-XL.  We’re looking forward to  seeing people wearing the shirts and getting our brands out there!
