Ethos is Thought Space Athletics’ premium clear plastic, moulded by MVP, and the TSA blend in the same class as Innova Champion and MVP Proton. Transparent and long-lasting. Nine moulds are listed in it.
That’s the plastic for keeping a mould’s flight.
Grip is the trade: slick when wet, stiff in the cold. Aura and Ethereal are the TSA blends for feel.
